Colts kicker Lou Michaels missed a 33-yard field goal attempt early in the third quarter, but the Colts got the ball back with great field position at midfield after the Vikings punted. Then on the second play of the Colts' ensuing drive, Morrall threw a pass to tight end John Mackey, who broke ahead of linebacker Roy Winston, caught the ball and then raced past safeties Karl Kassulke and Paul Krause to score on a 49-yard touchdown completion, giving the Colts a 14–0 lead. Vikings returner Clint Jones gave his team a chance to get back in the game with a 35-yard kickoff return to the Colts' 42-yard line. However, on the second play of the possession, Colts lineman Bubba Smith plowed into Kapp as he was winding up to throw a pass, knocking the ball out of his hand and right into the arms of linebacker Mike Curtis, who returned the fumble 60 yards to the end zone.
