Lions center Dominic Raiola has been suspended one game by the NFL after what appeared to be a blatant act of unsportsmanlike conduct during Sunday’s win over the Bears.

In the third quarter, a stumbling Raiola stomped on the right ankle of Bears defensive tackle Ego Ferguson. Ferguson was injured on the play but later returned.

After the game, Raiola claimed the contact was accidental. The NFL felt differently, however, suspending him Monday for repeated violations of player safety rules. NFL Media Insider Ian Rapoport reports that Raiola will appeal his punishment, and it’s expected to be heard Tuesday, per a source close to the player.
