AFC Championship, 1977: Denver 20 Oakland 17

Game information
Despite a poor day from veteran kicker Jim Turner, who missed three field goals and had an extra point blocked, Denver converted two second half turnovers into touchdowns to edge out the defending Super Bowl champion Raiders.

Denver was forced to punt on their opening drive, and Bucky Dilts's kick went just 21 yards to the Oakland 43-yard line. Aided by two Broncos penalties, including a running into the punter call that enabled Oakland to avoid a three and out, the Raiders subsequently drove to the Denver 2-yard line and scored with Errol Mann's 20-yard field goal. But on the Broncos' second drive, quarterback Craig Morton threw a 74-yard touchdown to wide receiver Haven Moses, who caught the ball along the right sideline and managed to break through a tackle attempt by Skip Thomas and stay in bounds on the way to the end zone. The score would remain 7–3 for the rest of the half, with Mann hitting the uprights on a 30-yard field goal try and Turner missing a 40-yard attempt. The Raiders also suffered a major setback when receiver Fred Biletnikoff went down with a separated shoulder.

Oakland's Carl Garrett returned the second half kickoff 62 yards to the Broncos 33-yard line. On first down, Ken Stabler tried to connect with Cliff Branch in the end zone, but Steve Foley barely managed to deflect the pass away. Then running back Mark van Eeghen was held to a 1-yard gain, Stabler threw a third down incompletion, and the Raiders decided to punt rather than risk a 49-yard field goal. Denver took after and drove deep into Raiders territory, with Moses hauling in a 41-yard reception to give the Broncos another scoring chance, but following a bad snap, Turner missed another field goal, this one from 31 yards. On the next play, Oakland's Clarence Davis lost a fumble that defensive end Brison Manor recovered at the Oakland 17-yard line. A short carry from fullback Jon Keyworth and Morton's 13-yard completion then moved the ball to the 2. Then running back Rob Lytle was hit in mid-air while trying to dive over the line by Raiders safety Jack Tatum, and lost the ball. Oakland nose tackle Mike McCoy appeared to recover the fumble, but the play was blown dead by an official on the opposite side of the field. The officials (chiefly Ed Marion) ruled that Lytle's forward progress was stopped before the fumble, even though replays clearly showed the ball was knocked free at the moment of contact. Denver retained possession. The Raiders were then penalized half the distance to the goal for arguing the call, and Keyworth scored a Denver touchdown on the next play to give Denver a 14–3 lead.

Later on, Denver recovered a muffed punt from Garrett on the Raiders 27-yard line. Right after the turnover, Morton appeared to throw a touchdown pass to Jack Dolbin, who made a rolling catch along the ground and then got up and headed for the end zone. However, officials ruled the ball had touched the ground before he secured the catch (replays appeared to contradict this) and it was called as an incompletion. Following two more incomplete passes, Turner missed his third field goal of the day, this time from 44 yards, and the Broncos came up empty.

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.

Moses was responsible for most of Denver's 217 yards gained through the air, finishing the game with 5 receptions for 168 yards and two touchdowns. Morton completed 10/20 passes for 224 yards and two touchdowns, with one interception. Stabler finished 17/35 for 215 yards and two touchdowns with one pick. Garrett returned 3 kickoffs for 111 yards and two punts for 5.

With his two touchdown catches along with his three against the Colts, Casper set a single post-season record for touchdowns by a tight end (5) which still stands to this day.

This was the first postseason meeting between the Raiders and Broncos.
