The NFL said Suh would escape suspension but faced the monetary sanction after his foot struck the groin of Houston Texans quarterback Matt Schaub during the Lions' 34-31 overtime Thanksgiving Day loss.
Suh was being hauled down during a pass rush when he made contact with Schaub. The blow sent the Texans signal-caller to the ground in pain.
The Lions player was suspended two games last year trying for to injure Green Bay Packers offensive lineman Evan Dietrich-Smith by stomping on his arm.
Suh is also facing off-field problems.
Lathrup Village, Mich., officials said Tuesday they were reviewing a Nov. 15 ticket he received for allegedly failing to use due care and caution while driving through the town.
Suh allegedly was traveling at a high rate of speed and then merged in front of other vehicles when his lane ran out.
The player has a long history of driving-related incidents, the Detroit News reported.
