Steelers' Polamalu practices, remains questionable

The Pittsburgh Steelers finally received good news about one of their injured stars, but strong safety Troy Polamalu's return isn't imminent.

Polamalu practiced Friday, his first in seven weeks, but was limited and is officially listed as doubtful on the injury report for Sunday's game against the Browns.

Polamalu has been hobbled by a calf injury he aggravated Oct. 7 against the Eagles.

Polamalu, 31, is in his 10th season. He played in the regular-season opener on Sept. 9 and returned for the Philadelphia game after three weeks, including the bye week Sept. 30. Coach Mike Tomlin said Polamalu's injury was "significant."
