Safety Troy Polamalu (knee) did not practice again on Thursday and now seems to be highly doubtful to play on Sunday. Guard Chris Kemoeatu (wrist) did not practice on Thursday after working fully on Wednesday and was added to the injury report. Cornerback Keenan Lewis (back) also sat out today after being limited on Wednesday. Defensive end Brett Keisel (neck), cornerback Anthony Madison (illness), running back Willie Parker (knee), wide receiver Hines Ward (hamstring), running back Rashard Mendenhall (hip) and wide receiver Mike Wallace (knee) all practice fully on Thursday and all should be good to go baring any setbacks.
For the Ravens on Thursday, tackle Jared Gaither (foot), linebacker Tavares Gooden (groin), linebacker Jarret Johnson (knee), long snapper Matt Katula (forearm) and safety Ed Reed (groin) all did not participate in the Thursday session. Wide receiver Mark Clayton (knee), safety K.J. Gerard (thigh) and nose tackle Kelly Talavou (knee) were all limited. Center Matt Birk (neck), wide receiver Justin Harper (foot), tight end Todd Heap (chest), defensive tackle Haloti Ngata (ankle), tight end L.J. Smith (ankle) and wide receiver Kelley Washington (ankle) all practiced fully on Thursday.
