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.

Ziggy Hood is expected to start in place of Smith at defensive end. Brett Keisel, who is returning from a knee injury, will start at the other defensive end position. Chris Hoke or Steve McClendon will start in place of Hampton at nose tackle.

Doug Legursky will start at left guard for Kemoeatu.
