PITTSBURGH » 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 the Kahuku grad 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 straight game with a sprained posterior cruciate ligament in his left knee, which has been slower to heal than the team expected. Polamalu hopes to play in the team's regular-season finale Jan. 3 in Miami.
