Early in the fourth quarter, Starr was knocked out of the game when he jammed the thumb on his throwing hand on a sack by Davidson. (Starr was replaced by Zeke Bratkowski, who was then sacked on his only pass attempt.) But later in the period, the Packers put the game completely out of reach when defensive back Herb Adderley intercepted a pass intended for Fred Biletnikoff and returned it 60 yards for a touchdown, making the score 33–7. Adderley laid back as the Raider end ran a curl route, then dashed in front of him to snare the ball and scored with the help of a crushing downfield block by tackle Ron Kostelnik.
