Updating a previous report, Pittsburgh Steelers QB Ben Roethlisberger (head) said he does not have a concussion and expects to practice Wednesday, Dec. 2, and play in Week 13 against the Indianapolis Colts. Meanwhile, the NFL and the Players Association are investigating the circumstances surrounding Roethlisberger sustaining a concussion in Week 12, according to sources. Roethlisberger played nine snaps after a hit to his head but was removed from the game later when he told doctors he was ‘having some vision problems,’ and he said that he still has a migraine.
