Pittsburgh's James Harrison intercepted a Kurt Warner pass on the goal line and returned the ball 100 yards to score a touchdown on the longest play in Super Bowl history. There was a flag on the play, a personal foul on Arizona, which allowed the touchdown to remain on the board. The score gave Pittsburgh a 17-7 lead heading into halftime, a deflating turn of events for the Cardinals, who appeared primed to take the lead, or at the very least tie the game. Cardinals receiver Larry Fitzgerald raced back to tackle Harrison as he reached the end zone, but the touchdown stood after a booth review from above.
