Near the end of the third quarter, Oakland finally caught a break when Garrett returned Dilts' 38-yard punt 4 yards to the Broncos 48-yard line. On the next play, Van Eeghen rushed for 13 yards. Following an incompletion, Stabler fired a pass to tight end Dave Casper, who made a falling catch, got back up, and took off for a 26-yard gain to the Denver 9. Two plays later, Stabler finished the drive with a 7-yard touchdown pass to Casper on the second play of the fourth quarter, cutting the score to 14–10. Denver responded by advancing the ball to the Raiders 11-yard line, only to have linebacker Floyd Rice intercept the ball from Morton and take it 11 yards back to the 22. Oakland now seemed primed to drive for a leading touchdown, but before they could get out of their own territory, Denver linebacker Bob Swenson made a clutch interception and returned the ball 14 yards to the Oakland 17-yard line. Two plays later, Moses made a sliding 12-yard catch of Morton's pass in the end zone, putting the Broncos ahead 20–10 after Turner's extra point was blocked. Oakland struck back with an 8-play, 74-yard drive to score on Casper's 17-yard touchdown catch to make it 20–17 with 3:16 left in regulation, but the Broncos' held the ball for the rest of the game and ran out the clock.
