A Thanksgiving day NFL football game in November 1998 ended with the Detroit Lions and the Pittsburgh Steelers tied at 16. Referee Phil Luckett made the toss to determine who would get the ball in overtime. As tapes later confirmed, Steelers fullback Jerome Bettis called tails and tails it was. Luckett, however, claimed to have heard "heads" and gave the ball to the Lions, who promptly drove to a game-winning 42-yard field goal.
[The NFL changed the coin-toss rule, decreeing that the call be made before the coin is tossed.]
