The Steelers' star safety hopped off the field early in the second quarter during Sunday's 16-14 victory over the Philadelphia Eagles. Polamalu didn't appear to have been hit, and Fox's Pam Oliver reported the safety wouldn't return. Ryan Mundy replaced Polamalu in the Steelers' lineup.

All-Pro linebacker James Harrison successfully returned to the Steelers' lineup for the first time this season without incident.
