The defending champion Pittsburgh Steelers gave the media an early diagnosis on star safety Troy Polamalu's injured left knee after the game Thursday. They said it was a sprained medial collateral ligament that would sideline Polamalu for three to six weeks.

The Pittsburgh Post-Gazette reports the team confirmed that Friday, but will not give any further updates on the injury status until Monday.

The Steelers will be challenged greatly without their best defensive player, and have yet to announce a roster move to cover for Polamalu's injury.

And the Post-Gazette opines that they probably won't since safety Roy Lewis, released late in camp, chose to sign with Seattle rather than sign with the Steelers practice squad.

Tyrone Carter filled in for Polamalu on Thursday night, and he figures to get that nod in a starting role until the Pro Bowler returns.

The first prognosis isn't always the most accurate, which may be why the Steelers are going to wait the weekend out before expanding on the timetable and exact extent of the injury.

But we'll keep and eye on this one, for sure, as it wouldn't surprise many if Polamalu returned much earlier than the three to six week period, considering his work ethic and toughness.
