With the Pittsburgh Steelers fast running out of games and his left knee still not healed, star safety Troy Polamalu isn't certain if he will be back this season.
Polamalu is hopeful of playing again, but he said Tuesday there is no definitive date for his return.
Polamalu's latest injury, to his posterior cruciate ligament, was initially expected to be less severe than the anterior cruciate ligament injury that kept him out of the Steelers' second through fifth games. But he won't play Thursday night in Cleveland, the fourth consecutive game he's missed with his latest injury.
The Steelers have 10 days off after Cleveland until their next game, and there is a chance the five-time Pro Bowl player could be ready to play Dec. 20 against Green Bay. However, Polamalu hasn't been cleared to practice.
Redskins cut kicker: The chip-shot miss against the New Orleans Saints has cost Washington Redskins kicker Shaun Suisham his job.
Suisham, the most accurate kicker in franchise history, was cut Tuesday by the Redskins, who replaced him with Graham Gano from the United Football League.
Suisham made his first 13 field goal attempts this season, but he had vital misses from 39 and 50 yards in the 7-6 loss to Dallas three games ago and was wide right Sunday on a 23-yarder that would have sealed a victory over the unbeaten Saints. New Orleans rallied to win 33-30 in overtime.
Portis placed on IR: The season is over for Washington running back Clinton Portis, who has not played since his concussion a month ago.
The Redskins placed Portis on injured reserve Tuesday after he had another round of tests by a specialist in Pittsburgh. Portis was hurt in a helmet-to-helmet hit against Atlanta on Nov. 8 and has missed four games.
Front office chief Vinny Cerrato says the team expects Portis to make a full recovery and return to the Redskins.
Bucs returner sidelined: Tampa Bay kick returner Clifton Smith will miss the rest of the season after his second concussion in less than two months.
The second-year pro was placed on injured reserve Tuesday, two days after he was hurt making a tackle on the opening kickoff of Sunday's 16-6 loss at Carolina.
