List of NFL retired numbers
Teams in the National Football League retire jersey numbers of players who either are considered by the team to have made significant contributions to that team's success, or who have experienced untimely deaths during their playing career. As with other leagues, once a team retires a player's jersey number, it never issues the number to any other player, unless the player or team explicitly allows it.
History
Since NFL teams began retiring numbers, 163 players have had their jersey number retired. The Chicago Bears and the New York Giants have the most retired numbers of the teams with 14 each.Reggie White is the only player whose number was retired by two teams. While Peyton Manning's number is only officially retired by the Indianapolis Colts, he received an acknowledgment when the Denver Broncos re-retired the number 18, which is officially retired under the name of Frank Tripucka. The Atlanta Falcons, Dallas Cowboys, and Las Vegas Raiders traditionally do not retire jersey numbers. The New Orleans Saints previously retired numbers, having done so for Jim Taylor and Doug Atkins, but under new ownership those numbers were unretired. Also without a retired jersey number are the Baltimore Ravens and the Houston Texans, though these teams are less than 30 years old: in this regard, the Texans do not retire numbers but honor player jerseys instead.
The Buffalo Bills under previous owner Ralph Wilson also did not retire jersey numbers, with the exception of Jim Kelly. This policy was reversed under Wilson's successor Terry Pegula.
Unlike Major League Baseball, the National Hockey League, and the National Basketball Association, the NFL has never retired a jersey number league-wide in honor of anyone.
The number 00 is no longer allowed, but was not retired in honor of any particular player; rather, the NFL's positional numbering system, instituted in 1973, does not allocate a position for players wearing that number. The NFL allowed 00 in the past, with Steve Bagarus, Jim Otto, and Ken Burrough being the only three players to have ever worn it. The number can be, and rarely is, used in the preseason when no other numbers for a player's position are available.
