Pittsburgh Steelers left guard Chris Kemoeatu will sit out Sunday's game against Green Bay with right wrist and right knee injuries.

Coach Mike Tomlin says Kemoeatu has been "playing one-handed" at times because of the wrist injury and that he needs a week off to heal. Kemoeatu will be replaced by undrafted rookie Ramon Foster.

Steelers safety Troy Polamalu will miss a fifth consecutive game with a sprained posterior cruciate ligament in his left knee, an injury that has been slower to heal than the team expected. Polamalu hopes to play in the Steelers' regular season finale Jan. 3 in Miami, but he could miss the rest of the season.
