PITTSBURGH — The Bengals have a 24-7 lead over the Steelers early in the fourth quarter. If they're going to hold on, they'll have to do it without one key starter. 

Cornerback Chidobe Awuzie is doubtful to return with a groin injury. Offensive tackle Riley Reiff suffered a left ankle injury, but he's expected to go back in the game. 

Darius Phillips replaced Awuzie. Isaiah Prince would step in for Reiff if he can't return.
