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