It was a rough first half from an injury standpoint for the Colts during their "Sunday Night Football" preseason game at Pittsburgh. Indianapolis lost DL Cory Redding early in the game to a leg injury, then OLB Robert Mathis was sent to the sideline with a shoulder strain. Finally, WR Austin Collie, with a history of concussions, took a blow to the head from Steelers ILB Larry Foote as he tried to haul in a pass over the middle. Collie reportedly was being tested for a concussion on the sideline and was not going to return to the game. Source: Pro Football Weekly
