With trainers looking at Andy Dalton in the fourth quarter and the score out of hand, the Bengals put in Bruce Gradkowski.
Dalton said after the game that he was fine and he looked to be walking normally in the locker room.
"He was hurting a little bit and we can't risk him getting hurt," AJ Green said. "We're still in the hunt for the playoffs. No sense in him getting hurt for the rest of the season."
