The NFL said the referee made a mistake: Troy Polamalu caught the ball. The league acknowledged Monday that referee Pete Morelli erred when he overturned on replay Polamalu's interception of a Peyton Manning pass Sunday in the playoff game between Pittsburgh and Indianapolis. Mike Pereira, the league's vice president of officiating, said in a statement that Morelli should have upheld the call, made with 5:26 left in Pittsburgh's win over the Colts. "He maintained possession long enough to establish a catch," Pereira said. "Therefore, the replay review should have upheld the call on the field that it was a catch and fumble."
