The 1963 NFL season was the 44th regular season of the National Football League. On April 17, NFL commissioner Pete Rozelle indefinitely suspended Green Bay Packers running back Paul Hornung and Detroit Lions defensive tackle Alex Karras for gambling on their own teams, as well as other NFL games; Hornung and Karras would miss the entire season. In addition, five other Detroit players were fined $2,000 each for placing bets on one game in which they did not participate. The season ended when the Chicago Bears defeated the New York Giants in the NFL Championship Game.
