MIAMI -- Pittsburgh Steelers safety Troy Polamalu and defensive end Brett Keisel are inactive for Sunday's game against the Miami Dolphins.
Polamalu practiced in a limited role this week for the first time in seven weeks. He has missed 11 full games and most of two others because of two left knee injuries. He hasn't played since a Nov. 15 game against the Cincinnati Bengals because of a sprained posterior cruciate ligament.
Keisel, who has a neck injury, was replaced in the starting lineup by Nick Eason.
Dolphins running back Ricky Williams is active for the game after being limited in practice because of a shoulder injury.
