The NFL continues to crack down on defenders who use the outlawed "horse-collar" tackle, and Chicago Bears' middle linebacker Brian Urlacher has been fined $7,500 for an incident in last Sunday's loss to the Minnesota Vikings. Urlacher is the second Bears' defensive player sanctioned this year for the illegal maneuver which was banned in 2005. Rookie defensive back Corey Graham was fined for using a horse-collar tackle in a Sept. 30 game against Detroit. He has appealed the fine.
