Green Bay Packers inside linebacker Sam Barrington picked up his second fine in three weeks ($16,537) for roughing Detroit quarterback Matthew Stafford in the third quarter of Sunday's game at Lambeau Field.
Barrington wasn't flagged on the play.
He was fined the same amount for a horse-collar tackle against Buffalo on Dec. 15.
Meanwhile, Lions running back Reggie Bush was fined $8,268 for grabbing the face mask of cornerback Casey Hayward during a sideline collision Sunday. But Packers linebacker Brad Jones wasn't fined for making contact with Stafford's helmet near the end of the first half.
