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.
Bet NFL Week 14
Polamalu is hopeful of playing again in 2009, 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.
With 10 days off until the next game, 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, much less play.
Oddsmakers from online sports book SBGGLOBAL.com have made the Steelers -10 point spread favorites Thursday night's game against the Cleveland Browns.
