Steelers fullback Franco Harris scored the winning touchdown on what became known as the Immaculate Reception. In a game that was mostly dominated by defense, the contest remained scoreless throughout the first half. On the opening drive of the second half, Pittsburgh drove 67 yards to take a 3–0 lead on Roy Gerela's 18-yard field goal. Following two Raiders drives that were shut down by Jack Ham's interception and a fumble recovery by Glen Edwards, Steelers defensive back Mike Wagner fell on a fumble by quarterback Ken Stabler (who had replaced injured starter Daryle Lamonica earlier in the game) at the Oakland 35. Five plays later, Gerela kicked a 29-yard field goal that gave Pittsburgh a 6–0 lead in the fourth quarter. Stabler responded by leading his team 80 yards to score on a 30-yard touchdown run with 1:13 left in the game.
