Baltimore starting cornerback Samari Rolle is listed as doubtful for Sunday's game with a thigh injury. Rolle got hurt in last week's divisional-round victory over the Tennessee Titans and missed practice all week.
Ravens backup cornerback Frank Walker likely will replace Rolle in the starting lineup. Reserve defensive back Corey Ivy also could play a bigger role in the secondary for Baltimore, which finished No. 2 in total defense in the regular season.
Pro Bowl defensive end/linebacker Terrell Suggs is listed as questionable with a shoulder injury. Suggs will be a game-time decision.
Suggs said he wants to try to play through the injury, but defensive coordinator Rex Ryan told ESPN's Rachel Nichols that Suggs has to prove to trainers before the game that he has enough strength to protect himself.
On Pittsburgh's side, safety Troy Polamalu (calf) and center Justin Hartwig (knee) are both listed as probable.
