Pittsburgh RB Willie Parker(shoulder) did not practice again on Thursday and the Pittsburgh Post-Gazette is reporting he will miss Week 10 against the Colts. Parker rushed for 71 yards on 21 carries against Washington last Monday night. He scored a touchdown. It was his first game back after missing four straight. Parker apparently hurt himself in the 3rd quarter but didn't feel the resulting pain until the next day. Mewelde Mooreis expected to start in his place.
