In the NFL, the horse-collar tackle results in a 15-yard major foul penalty and an automatic first down if committed by the defense, and the penalty is assessed as if it were a dead ball, after the play foul, if the opposing offense gains yards. It will often also result in a league-imposed fine on the player. Roy Williams was the first player suspended for repeated violations of the rule. The one-game suspension was given following a horse-collar tackle on Philadelphia Eagles quarterback Donovan McNabb that occurred on December 16, 2007, and it was Williams' third violation of the rule of the 2007 season.
