The Pittsburgh Steelers are a professional American football team based in Pittsburgh, Pennsylvania. They currently belong to the Northern Division of the American Football Conference (AFC) in the National Football League (NFL). The team has appeared in six Super Bowls, winning five of them, and thirteen Conference Championship Games winning six of them.

Originally named the Pittsburgh Pirates, the team along with the Philadelphia Eagles and the now-defunct Cincinnati Reds football team joined the NFL as 1933 expansion teams, after Art Rooney, Sr. paid a $2,500 fee. The team was renamed the Steelers in 1941 after the city's prominent steel industry to reflect the "blue collar" work ethic of the many Pittsburgh fans.

Franchise history

The Pittsburgh NFL team first took to the field on September 20, 1933, losing 23-2 to the New York Giants. Through the 1930s the Pirates never finished higher than second place in their division, or with a record better than .500 (1936). Pittsburgh did make history in 1938 by signing Byron White, a future justice on the U.S. Supreme Court to what was at the time the biggest contract in NFL history, but he only played one year with the Pirates before signing with the Detroit Lions.

In 1941, the team was renamed the Steelers after the city's prominence as a steel-making center. But the team maintained a long history of futility for the next three decades.

During World War II, the Steelers experienced player shortages. They twice merged with other NFL franchises in order to field a team. During the 1943 season, they merged with the Philadelphia Eagles forming the "Phil-Pitt Eagles" and were known as the "Steagles". This team went 5-4-1. In 1944 they merged with the Chicago Cardinals and were known as "Card-Pitt" and informally known as the "Car-Pitts" or "Carpets".

The Steelers made the playoffs for the first time in 1947, tying for first place in the division at 8-4 with the Philadelphia Eagles. This forced a tie-breaking playoff game at Forbes Field, which the Steelers lost 21-0. That would be Pittsburgh's last playoff game for 25 years.

Their luck changed with the hiring of coach Chuck Noll. Noll's most remarkable talent was in his draft selections, taking Hall of Famers "Mean" Joe Greene in 1969, Terry Bradshaw and Mel Blount in 1970, Jack Ham in 1971, Franco Harris in 1972, and finally, in 1974, the best draft in Steelers history, pulled the incredible feat of selecting four Hall of Famers in one draft year, Mike Webster, Lynn Swann, John Stallworth and Jack Lambert. This group of players formed the base of one of the greatest teams in NFL history, making the playoffs 8 seasons in a row and winning 4 Super Bowls.

The Steelers suffered a rash of injuries in the 1980 season and missed the playoffs with a 9-7 record. 1981 was no better, with an 8-8 showing. The team was then hit with the retirements of all their key players from the Super Bowl years. Mean Joe Greene retired after the 1981 season, Lynn Swann and Jack Ham after 1982, Terry Bradshaw and Mel Blount after 1983, and Jack Lambert after 1984.

In 1992 Chuck Noll retired and was succeeded by Kansas City Chiefs defensive coordinator Bill Cowher, a native of the Pittsburgh suburb of Crafton. Cowher led the Steelers to the playoffs in each of his first six seasons as coach, a feat that had only previously been accomplished by legendary coach Paul Brown of the Cleveland Browns. Overall, Cowher has taken his team to the playoffs in 10 out of his 14 seasons, including appearances in Super Bowl XXX in 1996 and the franchise's record-tying fifth Super Bowl win in Super Bowl XL in 2006. With their Super Bowl XL victory, the Steelers became the first sixth-seeded playoff team, since the NFL expanded to a 12-team postseason tournament in 1990, to win the Super Bowl.

Logo and uniforms

The original Steelers logo. It is primarily still used on the helmets. The newer, stylized Steelers logo. It is primarily used on the team's web site and other promotional materials.

The Steelers have used black and gold as it colors since the 1950s. Originally, the team wore solid gold helmets and black jerseys. Unlike most other cities, the colors are currently also used by the Pittsburgh Pirates baseball team and the Pittsburgh Penguins hockey team, making it the official team colors of every professional sports team in the city.

The Steelers logo was then introduced in 1962, and is based on the "Steelmark", originally designed for U.S. Steel, by Cleveland, Ohio based Republic Steel, and now owned by AISI. It consists of the word "Steelers" surrounded by three astroids (hypocycloids of four cusps). The original meanings behind the astroids were, "Steel lightens your work, brightens your leisure and widens your world" and later the colors came to represent the ingredients of steel, the yellow representing coal; the orange, ore; and the blue, steel scrap. While the "Steelmark" logo only contains the word "Steel", the Steelers were given special permission to add "-ers".

The Steelers are the only NFL team that puts their logo on only one side of the helmet (the right side). At first, it was a test to see how the logo appeared on their gold helmets, but its popularity led the team to leave it that way permanently. (It's also been rumored the team's longtime equipment manager, Jack Hart, wasn't happy with slapping the logo on so many helmets and refused to do both sides). [1][2] A year after introducing the logo, they switched to black helmets to make it stand out more.

The Steelers started to use the uniform design that they wear today since the late 1960s. The design consists of gold pants and either black jerseys or white jerseys. The helmet is solid black with a gold central stripe and small white uniform numbers on the forehead. Since the late 1990s, each player has worn a Steelers logo patch on left side of his jersey.

Franchise traditions

The "Terrible Towel" is a gimmick created by Myron Cope, a broadcaster, for the Steelers. Needing a way to excite the fans during a 1975 playoff game against the Baltimore Colts, Cope urged fans to take yellow dish towels to the game and wave them throughout.

Instead, the agency relies on other methods, including death certificates and urging physicians to send suspicious cases to the National Prion Disease Pathology Surveillance Center (NPDPSC) at Case Western Reserve University in Cleveland, which is funded by the CDC.
. In the U.S., the CDC has refused to impose a national requirement that physicians and hospitals report cases of the disease. Other Hall-of-Famers associated with Steelers. In the UK anyone with possible vCJD symptoms must be reported to the UK Creutzfeldt-Jakob Disease Surveillance Unit and so it is unlikely that any cases would be missed. Elected on the basis of performance with Steelers. As for vCJD in humans, autopsy tests are not always done and so those figures too are likely to be too low, but probably by a lesser fraction.

^At the end of the 2005 NFL season, the Steelers All-Time Record is 523-502-21 (including playoffs). It is noticeable that there are no cases reported in Australia and New Zealand where cattle are mainly fed outside on grass pasture and, mainly in Australia, non-grass feeding is done only as a final finishing process before the animals are processed for meat. Note: W = Wins, L = Losses, T = Ties. Even so, currently the only reliable test is examination of tissues during an autopsy. Needing a way to excite the fans during a 1975 playoff game against the Baltimore Colts, Cope urged fans to take yellow dish towels to the game and wave them throughout. Newer tests are faster, more sensitive, and cheaper, so it is possible that future figures may be more comprehensive. The "Terrible Towel" is a gimmick created by Myron Cope, a broadcaster, for the Steelers. Tests are also difficult as the altered prion protein has very small levels in blood or urine, and no other signal has been found.

Since the late 1990s, each player has worn a Steelers logo patch on left side of his jersey. At the opposite end of the scale, Japan tests all cattle at the time of slaughter. The helmet is solid black with a gold central stripe and small white uniform numbers on the forehead. For instance, in the EU the cattle tested are older (30 months+), while many cattle are slaughtered earlier than that. The design consists of gold pants and either black jerseys or white jerseys. The tests used for detecting BSE vary considerably as do the regulations in various jurisdictions for when, and which cattle, must be tested. The Steelers started to use the uniform design that they wear today since the late 1960s. The figures given above for BSE are certainly too low, and most likely by a considerable amount.

[1][2] A year after introducing the logo, they switched to black helmets to make it stand out more. BSE is the disease in cattle, whilst vCJD is the disease in people. (It's also been rumored the team's longtime equipment manager, Jack Hart, wasn't happy with slapping the logo on so many helmets and refused to do both sides). The following table summarizes reported cases of BSE and of vCJD by country. At first, it was a test to see how the logo appeared on their gold helmets, but its popularity led the team to leave it that way permanently. Indeed, US meat producer Creekstone Farms alleges that the USDA is preventing BSE testing from being conducted [10]. The Steelers are the only NFL team that puts their logo on only one side of the helmet (the right side). Even so, critics call the partial prohibitions insufficient.

While the "Steelmark" logo only contains the word "Steel", the Steelers were given special permission to add "-ers". [9] Compliance with the regulations was shown to be extremely poor before the discovery of the Washington cow, but industry representatives report that compliance is now 100%. The original meanings behind the astroids were, "Steel lightens your work, brightens your leisure and widens your world" and later the colors came to represent the ingredients of steel, the yellow representing coal; the orange, ore; and the blue, steel scrap. In February 2001, the USGAO reported that the FDA, which is responsible for regulating feed, had not adequately policed the various bans. It consists of the word "Steelers" surrounded by three astroids (hypocycloids of four cusps). [8] A proposal to end the use of cow blood, restaurant scraps, and chicken litter (fecal matter, feathers) in January 2004 was eventually scrapped, despite the efforts of some advocates of such a policy, who cite the fact that cows are herbivores, and that blood and fecal matter could potentially carry BSE. Steel, by Cleveland, Ohio based Republic Steel, and now owned by AISI. In addition, it is legal for ruminants to be fed byproducts from some of these animals.

The Steelers logo was then introduced in 1962, and is based on the "Steelmark", originally designed for U.S. However, the byproducts of ruminants can still be legally fed to pets or other livestock and poultry such as pigs and chickens. Unlike most other cities, the colors are currently also used by the Pittsburgh Pirates baseball team and the Pittsburgh Penguins hockey team, making it the official team colors of every professional sports team in the city. In 1997, regulations prohibited the feeding of mammalian byproducts to ruminants such as cows and goats. Originally, the team wore solid gold helmets and black jerseys. regulations only partially prohibit the use of animal byproducts in feed. The Steelers have used black and gold as it colors since the 1950s. However, U.S.

With their Super Bowl XL victory, the Steelers became the first sixth-seeded playoff team, since the NFL expanded to a 12-team postseason tournament in 1990, to win the Super Bowl. As a result, the use of animal byproduct feeds was never common, as it was in Europe. Overall, Cowher has taken his team to the playoffs in 10 out of his 14 seasons, including appearances in Super Bowl XXX in 1996 and the franchise's record-tying fifth Super Bowl win in Super Bowl XL in 2006. Soybean meal is cheap and plentiful in the United States. Cowher led the Steelers to the playoffs in each of his first six seasons as coach, a feat that had only previously been accomplished by legendary coach Paul Brown of the Cleveland Browns. [7]. In 1992 Chuck Noll retired and was succeeded by Kansas City Chiefs defensive coordinator Bill Cowher, a native of the Pittsburgh suburb of Crafton. Trace-backs revealed that this cow originated from a herd in Texas, making it the first BSE cow native to the United States.

Mean Joe Greene retired after the 1981 season, Lynn Swann and Jack Ham after 1982, Terry Bradshaw and Mel Blount after 1983, and Jack Lambert after 1984. Tests carried out at the USDA laboratory in Ames, Iowa indicated the presence of BSE, and after subsequent confirmation from the Weybridge Veterinary Laboratory in the United Kingdom, the USDA acknowledged the second case of BSE on June 24. The team was then hit with the retirements of all their key players from the Super Bowl years. On June 10, 2005, the USDA reported a possible case of BSE in the United States. 1981 was no better, with an 8-8 showing. No case of variant Creutzfeldt-Jakob disease has occurred in North America so far, except among those who have traveled to Europe. The Steelers suffered a rash of injuries in the 1980 season and missed the playoffs with a 9-7 record. [6].

This group of players formed the base of one of the greatest teams in NFL history, making the playoffs 8 seasons in a row and winning 4 Super Bowls. Japanese inspectors found material from cattle backbone in three of 41 boxes in a 858-pound shipment of beef from Atlantic Veal & Lamb. Noll's most remarkable talent was in his draft selections, taking Hall of Famers "Mean" Joe Greene in 1969, Terry Bradshaw and Mel Blount in 1970, Jack Ham in 1971, Franco Harris in 1972, and finally, in 1974, the best draft in Steelers history, pulled the incredible feat of selecting four Hall of Famers in one draft year, Mike Webster, Lynn Swann, John Stallworth and Jack Lambert. Brooklyn-based Atlantic Veal & Lamb inspectors failed to notice there was bone material included in a shipment of veal to Japan. Their luck changed with the hiring of coach Chuck Noll. [5] It was, however, quick to reinstate the ban. That would be Pittsburgh's last playoff game for 25 years. Japan lifted its ban on US beef in December 2005.

This forced a tie-breaking playoff game at Forbes Field, which the Steelers lost 21-0. [4]. The Steelers made the playoffs for the first time in 1947, tying for first place in the division at 8-4 with the Philadelphia Eagles. Notwithstanding, Japanese beef exports, chiefly the expensive wagyu, have been banned in the United States since Japan experienced its first case of BSE in January 2001. In 1944 they merged with the Chicago Cardinals and were known as "Card-Pitt" and informally known as the "Car-Pitts" or "Carpets". Since Japan and South Korea are the first- and third-largest importers of US beef, respectively, the economic impact of their bans is significant both for American cattle ranchers and for Japanese and Korean beef consumers. This team went 5-4-1. beef until the authorities can be assured of its safety.

During the 1943 season, they merged with the Philadelphia Eagles forming the "Phil-Pitt Eagles" and were known as the "Steagles". discovery of BSE in 2003, Japan and South Korea instituted temporary bans on the import of U.S. They twice merged with other NFL franchises in order to field a team. Shortly after the U.S. During World War II, the Steelers experienced player shortages. surveillance relied on a test that gave results only after two weeks, after which time the meat from an animal usually has all been sold. But the team maintained a long history of futility for the next three decades. Until the switch, U.S.

In 1941, the team was renamed the Steelers after the city's prominence as a steel-making center. authorities called for a switch to the testing procedure that is used in the United Kingdom, which yields its results in one day. Supreme Court to what was at the time the biggest contract in NFL history, but he only played one year with the Pirates before signing with the Detroit Lions. U.S. Pittsburgh did make history in 1938 by signing Byron White, a future justice on the U.S. The meat of the BSE-positive cow went to market, but some of it was successfully recalled before it was sold to consumers. Through the 1930s the Pirates never finished higher than second place in their division, or with a record better than .500 (1936). Only 200,000 cows slaughtered in 2003 were downers.

The Pittsburgh NFL team first took to the field on September 20, 1933, losing 23-2 to the New York Giants. [3] Therefore it is not clear how effective the ban is in reducing the number of infected cattle consumed. . Furthermore, there is some dispute as to whether the cow was a downer or not. The team was renamed the Steelers in 1941 after the city's prominent steel industry to reflect the "blue collar" work ethic of the many Pittsburgh fans. While the Washington cow that tested positive for BSE was reportedly unable to stand, veterinarians say the condition was unrelated to BSE. paid a $2,500 fee. The government plans to double the number of cattle tested in 2004, and has banned the use of "downer cows" for human consumption.

Originally named the Pittsburgh Pirates, the team along with the Philadelphia Eagles and the now-defunct Cincinnati Reds football team joined the NFL as 1933 expansion teams, after Art Rooney, Sr. authorities have very little idea of how many American beef cattle might have the disease. The team has appeared in six Super Bowls, winning five of them, and thirteen Conference Championship Games winning six of them. As a result, U.S. They currently belong to the Northern Division of the American Football Conference (AFC) in the National Football League (NFL). Therefore, it is possible that even among those cattle that are tested and classified as negative, a proportion nevertheless may be contagious. The Pittsburgh Steelers are a professional American football team based in Pittsburgh, Pennsylvania. Current tests reveal the presence of misshaped prions when they are abundant, but it is not known how far the disease must progress in an individual to transmit it to others.

National Football League (1933-present). [2] Agriculture Secretary Ann Veneman called the discovery "a clear indication that our surveillance and detection program is working." However, the United States tested only 20,526 cows in 2003 out of the roughly 35 million slaughtered. Bill Cowher (1992-Present). On December 23, 2003, the first case of BSE in the United States was found in a single Holstein cow in Mabton, Washington, although trace-backs later revealed that this cow originated from a Canadian herd. Chuck Noll (1969-1991). The United States also issued a temporary ban on all Canadian beef. Bill Austin (1966-1968). The animal was destroyed after being declared unfit for consumption.

Mike Nixon (1965). It occurred in a single older cow that may have contracted the disease from contaminated feed in earlier years. Raymond "Buddy" Parker (1957-1964). The second was reported in Canada on May 20, 2003. Walt Kiesling (1954-1956). The first was in 1993, involving an animal born in Britain. Joe Bach (1952-1953). As of January 2005, five BSE-infected cattle have been identified in North America.

John Michelosen (1948-1951). regarding a possible risk of transmission of the BSE agent in gelatin products.". Jock Sutherland (1946-1947). that there were some licensed surgical sutures derived from French bovine material." Concerns were also raised: ".. Jim Leonard (1945). expressed concerns about the possible transmission of the BSE/scrapie agent to man through use of certain cosmetic treatments." Sources in France reported to the British Medicines Control Agency: ".. Walt Kiesling (1941-1944). there was no insulin sourced from cattle in the UK or Ireland and that the situation in other countries was being monitored." In 1991 a European Community Commission: "..

Bert Bell (1941). no licensing action is required at present in regard to products produced from bovine material or using prepared bovine brain in nutrient media and sourced from outside the United Kingdom, the Channel Isles and the Republic of Ireland provided that the country of origin is known to be free of BSE, has competent veterinary advisers and is known to practise good animal husbandry." In 1990 the British Diabetic Association became concerned regarding the safety of bovine insulin and the government licensing agency assured them that: ".. Aldo Donelli (1941). use of bovine insulin in a small group of mainly elderly patients was noted and it was recognised that alternative products for this group were not considered satisfactory." A medicines licensing committee report that same year recommended that: ".. Walt Kiesling (1939-1940). identify relevant manufacturers and obtain information about the bovine material contained in children’s vaccines, the stocks of these vaccines and how long it would take to switch to other products." It was further reported that the: ".. John McNally (1937-1939). "..

Joe Bach (1935-1936). On May 7, 1999 in his written statement number 476 to the BSE Inquiry, David Osborne Hagger reported on behalf of the Medicines Control Agency that in a previous enquiry the Agency had been asked to:. Luby DiMelio (1934). During the course of the investigation into the BSE epidemic, an enquiry was also made into the activities of the Department of Health and its Medicines Control Agency. Forrest Douds (1933). [1]. Josh Miller. In 2005 a controversial paper in The Lancet suggested that BSE might have originated in British cattle when they ate imported animal feed that included infected human remains from Hindu funeral ceremonies in India.

Rod Woodson. So far nothing is known about the relative transmissibility of the two disease strains of BSE prion. Dwight White. But cruder measures yield a "biochemical signature" by which the newly discovered cattle strain appears different from the familiar one, but similar to the clumped prions in humans with traditional CJD (Creutzfeldt-Jakob Disease).The finding of a second strain of BSE prion raises the possibility that transmission of BSE to humans has been underestimated, because some of the individuals diagnosed with spontaneous or "sporadic" CJD may have actually contracted the disease from tainted beef. Supreme Court Justice). Very little is known about the shape of disease-causing prions, because their insolubility and tendency to clump thwarts application of the detailed measurement techniques of structural biology. Byron White (U.S. In other words, this implies a second strain of BSE prion.

Bobby Walden. In 2004 researchers reported evidence of a second contorted shape of prions in a rare minority of diseased cattle. Yancy Thigpen. As a result the full extent of the human vCJD outbreak is still not fully known. Kordell Stewart. This is attributed to the long incubation period for prion diseases, which are typically measured in years or decades. Andy Russell. Although the BSE epidemic was eventually brought under control by culling all suspect cattle populations, people are still being diagnosed with vCJD each year (though the number of new cases currently seems to be dropping).

Eric Pegram. It is estimated that 400,000 cattle infected with BSE entered the human food chain in the 1980s. Actor Ed O'Neill was signed by the Steelers as a free agent in 1969, but was subsequently cut during training camp. Disease incidence also appears to correlate with slaughtering practices that led to the mixture of nervous system tissue with hamburger and other beef. Neil O'Donnell. For many of the vCJD patients, direct evidence exists that they had consumed tainted beef, and this is assumed to be the mechanism by which all affected individuals contracted it. Gerry Mullins. Up to date statistics on all types of CJD are published by the UK CJD Surveillance Centre in Edinburgh.

Bam Morris. There is also some concern about those who work with (and therefore inhale) cattle meat and bone meal, such as horticulturists, who use it as fertilizer. Chris Fuamatu-Ma'afala. Three cases of vCJD occurred in people who had lived in or visited Britain--one each in Ireland, Canada and the United States. Ray Mansfield. Of the 157 cases of vCJD in humans so far, 148 occurred in the United Kingdom, 6 in France, and one in Italy. Greg Lloyd. This is a separate disease from 'classical' Creutzfeldt-Jakob disease, which is not related to BSE and has been known about since the early 1900s.

Louis Lipps. Following an epidemic of BSE in Britain, 157 people (as of 2004) acquired and died of a disease with similar neurological symptoms subsequently called vCJD, or (new) variant Creutzfeldt-Jakob disease. Tim Lester. While other European countries like Germany required said animal byproducts to undergo a high temperature steam boiling process, this requirement had been eased in Britain as a measure to keep prices competitive. Carnell Lake. A contributing factor seems to have been a change in British laws that allowed a lower temperature sterilization of the protein meal. Jon Kolb. A change to the rendering process in the early 1980s may have resulted in a large increase of the infectious agents in the cattle feed.

Levon Kirkland. However, soybeans do not grow well in Europe, so cattle raisers throughout Europe turned to the less expensive animal byproduct feeds as an alternative. Ernie Holmes. Worldwide, Soybean meal is the primary plant-based protein supplement fed to cattle. Merril Hoge. The use of meat and bone meal as a protein supplement in cattle feed was widespread in Europe prior to about 1987. Greenwood. The tissues that contain most of the pathogenic molecules are those of the brain and the nervous system, although infectious amounts have been shown experimentally to be present elsewhere, such as in blood.

L.C. As more animals became ill, more infectious tissue got into the feed, and so the number of cases reached epidemic proportions. Kevin Greene. This practice allowed the accumulation of prions over many generations. Eric Green. Prior to the BSE epidemic, cattle were fed with meat and bone meal, a high-protein substance obtained from the remnants of butchered animals, including cows and sheep. Joe Gilliam. However, sheep and cattle TSEs are quite different and it is now thought more likely that BSE could have originated with a case of sporadic BSE in a single bovine.

Jason Gildon. It was first believed to have originated in sheep, in which the related prion disease scrapie is common (such diseases collectively are called "transmissible spongiform encephalopathies" or TSEs). Roy Gerela. The British BSE epidemic in cattle was recognised in 1986. Frenchy Fuqua. These aggregate to form dense plaque fibers, which lead to the microscopic appearance of "holes" in the brain, degeneration of physical and mental abilities and ultimately death. Barry Foster. In the brain these proteins cause native cellular prion protein to deform into the infectious state which then goes on to deform further prion protein in an exponential cascade.

Amos Zereoue. Transmission can occur when healthy animals consume tainted tissues from others with the disease. Buddy Dial. Most TSEs, however, occur sporadically in animals that do not have a prion protein mutation. Dermontti Dawson. TSEs can arise in animals that carry a rare mutant prion allele, which expresses prions that contort by themselves into the disease-causing shape. Bennie Cunningham. BSE is a type of transmissible spongiform encephalopathy (TSE).

Craig Colquitt. Misshapen ("misfolded") prion proteins carry the disease between individuals and cause deterioration of the brain. Plaxico Burress. Unlike other kinds of infectious disease which are spread by microbes, the infectious agent in BSE is a specific type of protein. Bubby Brister. . Rocky Bleier. While never having killed cattle on a scale comparable to other dreaded livestock diseases, such as foot and mouth and rinderpest, BSE has attracted wide attention because people assume humans can contract the disease, but it has never been proven that BSE has any link to variant Creutzfeld-Jakob disease (vCJD), sometimes called new variant Creutzfeld-Jakob disease (nvCJD), a human brain-wasting disease.

Kendrell Bell. The disease appears transmissible to humans. Matt Bahr. Bovine spongiform encephalopathy (BSE), commonly known as mad cow disease, is a fatal, neurodegenerative disease of cattle, which infects by a mechanism that shocked biologists on its discovery in late 20th century. Gary Anderson. Walter Abercrombie.

Mike Tomczak. The number hasn't been used since. According to legend, the equipment manager--who assigns jersey numbers to new players--later stripped Seabaugh of the number because the player "wasn't Jack Ham". 59 was used once in 1984 by Todd Seabaugh, who played one season with the team.

Note: After Jack Ham retired, no. Used four times officially since Mel Blount's retirement, most recently to safety Scott Shields in 2000. 47 has been issued during the preseason regulary, and on some occasions to the final 53-man roster. Note: No.

31. Since Donnie Shell's retirement after the 1987 season, Logan is the only Steeler to wear no. 31 is currently being used by backup safety Mike Logan, a native of the Pittsburgh suburb of McKeesport, Pennsylvania, and is currently in his fifth season with the Steelers. Note: No.
