Steelers S Polamalu's status uncertain for Sunday's game vs. Chiefs

PITTSBURGH -- The Pittsburgh Steelers have not yet updated the condition of star safety Troy Polamalu, who injured his left knee for the second time this season during their 18-12 loss to Cincinnati.

Polamalu missed four games after tearing the medial collateral ligament in his left knee Sept. 10 against Tennessee. He played three games before hurting the knee again during the Bengals' opening drive on Sunday.

The Steelers did not disclose the results of Polamalu's MRI exam, but he is not believed to have been as badly injured as he previously was. The Steelers (6-3) play Sunday at Kansas City (2-7).

Following a Sunday game, the Steelers usually do not update injuries until coach Mike Tomlin meets with reporters on Tuesday.
