The Pittsburgh Steelers defense continues to be banged up, as Troy Polamalu and Lamarr Woodley missed practice Tuesday and are both expected to miss Thursday night's matchup against the Tennessee Titans.

Polamalu has already been ruled out due to the same calf injury that caused him to miss a pair of games earlier this year, which he reaggravated Sunday against the Philadelphia Eagles. Woodley's status is less certain, but he missed practice Tuesday and probably will not be ready to go Thursday with the short turnaround.

For James Harrison and Rashard Mendenhall, each who made their season debuts Sunday, the outlook is better: they're expected to be good to go against Tennessee, but were both limited in practice. Mendenhall had ACL surgery in the offseason and Harrison had minor arthroscopic knee surgery during training camp that kept him out longer than expected.

Before last week's game, the Steelers had a week off to recuperate thanks to a bye in Week 4 that allowed Polamalu, Harrison, and Mendenhall to return. This week, they only have three days.
