Polamalu limped off the field following a fumble by Philadelphia quarterback Michael Vick. The team said Polamalu's return was questionable, but the 2010 NFL Defensive Player of the Year watched the entire second quarter from a seat on the bench and did not move. He was replaced by backup Ryan Mundy.

Polamalu missed each of Pittsburgh's previous two games after injuring the calf in a season-opening loss in Denver. The seven-time Pro Bowler had five tackles in the Steelers' Week 1 loss against the Broncos, which before Sunday was the only game he had played in this season.

The Steelers also lost linebacker LaMarr Woodley with a strained right hamstring. His return was questionable.

The right calf has been a troublesome injury for Polamalu. It's the same calf he hurt in the playoffs last season. A tender right calf kept him out of practice leading up to the divisional playoff game at Denver.
