"Detroit Lions quarterback Matthew Stafford and guard Rob Sims were fined $7,500 apiece for their roles in Sunday's skirmish with the Chicago Bears.

Separately, Lions rookie defensive tackle Nick Fairley was fined $15,000 for roughing the passer when he drove Bears quarterback Jay Cutler into the ground.

Stafford tossed Bears cornerback D.J. Moore to the ground while trying to fend off a block after his third interception of the game early in the fourth quarter.

Moore retaliated by hitting Stafford while he knelt on the ground, and Sims jumped in the pile as players from both benches spilled onto the field.

Stafford said he's not sure whether he'll appeal the fine, which was assessed for "grabbing an opponent by the helmet opening."

Moore was fined $15,000 for hitting Stafford after the play."
