Game summaries Week 1: at Kansas City Chiefs The Dolphins opened the season against the Chiefs in the first regular season game at
Arrowhead Stadium. In the
Divisional Round the year prior, Miami defeated Kansas City at
Kansas City Municipal Stadium in double overtime, the longest game in NFL history. On the Chiefs' first drive, Miami safety
Dick Anderson recovered an
Ed Podolak fumble, leading to a seven-play, 57-yard drive capped by a 14-yard touchdown from
Bob Griese to
Marlin Briscoe.
Lloyd Mumphord blocked a
Jan Stenerud field goal attempt on Kansas City's ensuing drive. Late in the second quarter, the Dolphins scored twice in quick succession – a 47-yard
Garo Yepremian field goal and a two-yard
Larry Csonka run following an interception by
Jake Scott. The Chiefs did not score until a 40-yard field goal by Stenerud late in the third quarter, and a touchdown from
Len Dawson to
Willie Frazier was the only score of the fourth quarter as Miami won 20–10.
Week 2: vs. Houston Oilers The
Orange Bowl's new
Poly-Turf field and intermittent rains led to slippery conditions for Miami's week 2 meeting with Houston. Less than two minutes in,
Bill Stanfill returned a
Hoyle Granger fumble to Houston's one-yard line to set up a
Jim Kiick touchdown. Minutes later, Houston quarterback
Dan Pastorini muffed the ball in punt formation; the Dolphins recovered again and
Mercury Morris scored four plays later. Garo Yepremian's subsequent extra point attempt was blocked, his first miss after seventy-five consecutive successful attempts. Miami engineered another four-play scoring drive on its following possession, using a 30-yard
Paul Warfield reception to set up a short Larry Csonka touchdown and give the Dolphins a 20–0 halftime lead. Pastorini completed three of ten passes for minus-ten yards in the first half. A nine-play, 76-yard drive to open the second half pushed Miami further ahead.
Week 3: at Minnesota Vikings The first-ever meeting between the Dolphins and Vikings began with a long first-quarter touchdown from
Fran Tarkenton to
John Gilliam; Minnesota held this 7–0 lead into halftime. Tim Foley intercepted Tarkenton early in the third quarter, setting up a 51-yard Garo Yepremian field goal. A second Yepremian field goal cut Minnesota's lead to one point, but the Vikings responded with thirteen-play drive which ended in a touchdown on the first play of the fourth quarter. Minnesota quickly regained possession by intercepting Bob Griese, but two sacks of Tarkenton kept Minnesota out of field goal range and the game at 14–6. On Miami's ensuing drive, a 22-yard pass from wide receiver Marlin Briscoe to
Jim Mandich set up another 51-yard Yepremian field goal.
Week 4: at New York Jets The Jets received the opening kickoff and quickly marched 65 yards downfield, taking a 7–0 lead when a
Cliff McClain fumble was recovered by guard
Randy Rasmussen in the end zone. New York maintained this advantage until early in the second quarter when a 16-yard touchdown pass from Bob Griese to
Howard Twilley tied the game. A six-yard Jim Kiick touchdown run gave Miami a 14–7 lead just before halftime. A field goal early in the third quarter increased Miami's lead to ten points. On New York's subsequent drive,
Joe Namath found
Jerome Barkum for a 52-yard gain which gave the Jets first-and-goal at the one-yard line. However, two penalties and three failed attempts forced New York to settle for an 18-yard
Bobby Howfield field goal, cutting the lead to 17–10. Early in the fourth quarter, Miami capitalized on a long pass interference penalty against
Steve Tannen with a second Jim Kiick touchdown run. Miami fumbled a punt deep in its own territory in the fourth quarter and allowed New York cut the lead to 24–17, but a late field goal put the game out of reach as the Dolphins won 27–17. In the third quarter, Morrall's second touchdown pass increased the lead to 24–3. A late San Diego touchdown made the final score 24–10 as the Dolphins moved to 5–0.

Week 6: vs. Buffalo Bills The Dolphins remained at home during week 6 for a game against the division rival
Buffalo Bills. Miami scored a touchdown on the opening drive, capped off by a five-yard run by Mercury Morris. After regaining possession later in the first quarter, the Dolphins managed to reach the Bills seven-yard line. However, four failed attempts at reaching the end zone gave the Bills possession again. Then, in the second quarter, Dolphins running back Jim Kiick fumbled the ball, recovered by
Alvin Wyatt of the Bills. This ultimately set up a 35-yard field goal by Buffalo's
John Leypoldt. Shortly after, Bills linebacker
Ken Lee intercepted a pass from Earl Morrall and returned it for a touchdown. Late in the second quarter, Morrall attempted to throw a lateral pass, but fumbled and Buffalo defensive tackle
Don Croft secured the ball. Leypoldt then kicked a 34-yard field goal, allowing the Bills to lead 13–7 at halftime. Dolphins tackle
Manny Fernandez strip-sacked Bills quarterback
Dennis Shaw at the Buffalo 10-yard line on the first play of the third quarter. Miami fullback Larry Csonka then ran 10 yards into the end zone, allowing the Dolphins to take a 14–13 lead. A few minutes after this transpired, Dolphins cornerback

Jim Bailey blocked Yepremian's extra point attempt. Later in the second quarter, Dolphins defensive back Lloyd Mumphord blocked
Boris Shlapak's field goal attempt. The second quarter then ended after Yepremian kicked a 24-yard field goal. The Dolphins led 16–0 after the first half. The game's final score occurred in the third quarter.
Bruce Laird of the Colts was returning a punt but fumbled the ball, which was recovered by
Hubert Ginn of the Dolphins at Baltimore's 20 yard line. After a few more plays, Morris scored a seven-yard rushing touchdown, followed by a Yepremian extra point. Miami won the game with a score of 23–0 and improved to 7–0 at the halfway point of the regular season. The Bills then overtook the Dolphins on a drive capped off by quarterback
Dennis Shaw throwing a 13-yard pass to running back
Randy Jackson, although
John Leypoldt's extra point attempt would be blocked. Buffalo now led Miami by a score of 6–3.

Tim Foley intercepted Shaw at Miami's 20-yard line. Miami increased their lead again in the third quarter with a seven-yard pass from Morrall to tight end
Marv Fleming. The antecedent drive included several long runs and an
unsportsmanlike conduct penalty against the Bills. Later in the third quarter, Leypoldt kicked a 28-yard field goal, cutting their deficit to 23–16 at the end of the period.

With neither team able to accumulate more points after that drive, the game ended as a 30–16 win for the Dolphins. Of note, Morris surpassed 100 rushing yards in a game for only the second time in his professional football career. On the third play of the game, Dolphins safety Dick Anderson intercepted Patriots quarterback Jim Plunkett at New England's 26-yard line. Anderson returned the ball to the New England four-yard line before fumbling. Although it appeared that the Patriots may have recovered the fumble, the officiating crew ruled that they did not. Dolphins running back Mercury Morris then scored a touchdown on a four-yard rush. On just the fifth offensive play for the Dolphins, Morris again scored a 4-yard rushing touchdown. Miami scored on every possession they had during the first half, leading the Patriots 31–0 at intermission. In the third quarter, Morrall threw a 16-yard pass to Marlin Briscoe, increasing the Dolphins lead to 38–0.
