Polamalu is listed with an ankle injury, but also dealt with an Achilles' injury that kept him out of two of the Steelers' final regular-season games. Polamalu returned to face the Cleveland Browns in Week 17 and will be ready to go Saturday following almost two weeks of rest thanks to the second-seeded Steelers' bye week in the wild-card round.
Cornerback Bryant McFadden also participated fully in Friday's practice and is listed as probable.
As expected, defensive end Aaron Smith is doubtful with a triceps injury.
The Ravens listed three players as questionable, including center Matt Birk, who is dealing with a knee injury and did not participate in Friday's practice.
Linebacker Tavares Gooden (shoulder) and wide receiver Donte Stallworth (illness) are both probable.
