PITTSBURGH -- Pittsburgh Steelers quarterback Ben Roethlisberger practised Friday despite being limited by his slightly separated right shoulder and may be able to play Sunday against the Indianapolis Colts.

Steelers coach Mike Tomlin said earlier in the week it might be a game-time decision whether Roethlisberger or backup Byron Leftwich starts against the Colts (4-4), but Roethlisberger is listed as probable.

Roethlisberger sat out the second half of the Steelers' 23-6 victory in Washington on Monday night after aggravating the injury on a one-yard touchdown run. The injury occurred in the Steelers' opener on Sept. 7 and has bothered him since. Leftwich played the second half, throwing a touchdown pass while leading two TD drives.

Roethlisberger sat out practice Wednesday and Thursday before working out Friday.

Running back Willie Parker may miss the game with a shoulder injury, the fifth game he would miss in the Steelers' last six. Parker returned from a four-game layoff with a sprained knee to rush for 71 yards against the Redskins, but did not practice all week and is listed as doubtful.

The Steelers (6-2) also may be without linebacker LaMarr Woodley, who injured his calf against the New York Giants on Oct. 26, but was able to play against Washington. He is listed as questionable.

Woodley, third in the AFC with 9 1/2 sacks, was fined US$10,000 on Friday for slamming Washington quarterback Jason Campbell to the ground. Campbell struck his head on the turf when hit.
