a safety, giving Pittsburgh a 2–0 lead. It was the first safety scored in Super Bowl history. The Vikings forced a three-and-out, then threatened to score when Tarkenton led them on a 55-yard drive to the Steelers' 20-yard line. With 1:17 left in the half, Tarkenton threw a pass to receiver John Gilliam at the 5-yard line, but Steelers safety Glen Edwards hit him just as he caught the ball. The ball popped out of his hands and right into the arms of Mel Blount for an interception. The half ended with the Steelers leading 2–0, the lowest halftime score in Super Bowl history and lowest possible, barring a scoreless tie. Third quarter On the opening kickoff of the second half, Minnesota's Bill Brown lost a fumble on an unintentional squib kick after Gerela slipped on the wet field and only extended his leg halfway for the kick. Marv Kellum recovered the ball for Pittsburgh at the Vikings' 30-yard line. Franco Harris then moved the ball to the 6-yard line with a 24-yard run. After being tackled for a three-yard loss, Harris carried the ball for nine yards and a touchdown, giving the Steelers a 9–0 lead. After an exchange of punts, Minnesota got the ball back on their own 20-yard line. On the second play of drive, Tarkenton's pass was deflected behind the line of scrimmage by Pittsburgh defensive lineman L. C.

Officials ruled Tarkenton's first pass attempt was a completion to himself, and thus his second attempt was an illegal forward pass. After the penalty, facing third and 11, Minnesota got the first down with running back Chuck Foreman's 12-yard run. Three plays later, Tarkenton completed a 28-yard pass to tight end Stu Voigt at the Steelers' 45-yard line. But White deflected Tarkenton's next pass attempt, and Joe Greene intercepted the ball, ending the Vikings' best offensive scoring opportunity. Fourth quarter Early in the fourth quarter, the Vikings got another scoring opportunity when Minnesota safety Paul Krause recovered a fumble from Harris on the Steelers' 47-yard line. On the next play, a deep pass attempt from Tarkenton to Gilliam drew a 42-yard pass interference penalty on Pittsburgh defensive back Mike Wagner that moved the ball up to the 5-yard line. Once again, the Steelers stopped them from scoring when Greene
