Starting defensive linemen Casey Hampton (shoulder) and Aaron Smith (foot) and starting left guard Chris Kemoeatu (knee) will not play in Sunday's game against the Tennessee Titans. Also ruled out are reserve running back Mewelde Moore (ankle) and reserve linebacker Jason Worilds (quadriceps). Starting running back Rashard Mendenhall (hamstring) is questionable as is reserve defensive back Cortez Allen (ankle). Quarterback Ben Roethlisberger (foot) is listed as probable. Chris Hoke or Steve McClendon will start in place of Hampton at nose tackle. Source: Pittsburgh Post-Gazette
I don't think he will play, if he does it will only be emergency 3rd so they dont have to bring up John Clay off the practice squad.
Yes. MEndenhall didn't practice Wednesday or Thursday and practiced a little today. They are saying he's a game time decision.
