For the second time this season (and the third time in two years), Dallas Cowboys strong safety Roy Williams, whose persistent use of the so-called "horse-collar" tackle, has been fined by the league for using the illegal technique. The NFL banned the dangerous maneuver in 2005. Williams was fined $15,000 on Friday for a hit that he made on Buffalo rookie tailback Marshawn Lynch in Monday night's victory over the Bills. Earlier this season, the league fined Williams $12,500 for a horse-collar tackle on tight end Desmond Clark in the Sept. 23 game against the Chicago Bears. By fining Williams for his actions in the Monday game, the league unwittingly conceded that the officiating crew led by referee Peter Morelli erred in its call by imposing just a five-yard facemask penalty on the Dallas safety.
