Suh says he plans to appeal.
The penalty came in the fourth quarter Sunday when Suh sent Cutler to the ground with what appeared to be a hard shove to the upper back after the quarterback ran for 8 yards. Referee Ed Hochuli called the play "an unnecessary non-football act." Lions coach Jim Schwartz disagreed with the call.
Suh didn't confirm the amount of the fine, but a person with knowledge of the fine, speaking on condition of anonymity because the league hadn't announced it yet, confirmed it was $15,000.
