Troy Polamalu practices, still uncertain

PITTSBURGH -- Steelers safety Troy Polamalu practiced Friday for the first time in three weeks and was listed as questionable for Pittsburgh's game in Cleveland.

Polamalu has missed the past two games with a right Achilles tendon injury. The team's medical staff wants to see how he responds to Friday's practice before deciding whether he can play Sunday.

Polamalu was selected this week by his teammates as the Steelers' most valuable player, the first time in his career he was chosen. He also was picked for his sixth Pro Bowl.

Information from The Associated Press and ESPN.com's James Walker was used in this report.
