Divisional Round, 1973: Miami 34 Cincinnati 16

Game information
The Dolphins outgained Cincinnati in total yards, 400–194, and first downs, 27–11, while also scoring on three of their first four possessions and shutting out the Bengals in the second half. The Dolphins racked up 241 yards on the ground, including 106 from Mercury Morris and 71 from Larry Csonka, while receiver Paul Warfield caught 5 passes for 95 yards and a score.

Miami dominated the game early on, scoring on their opening drive with Bob Griese's 13-yard touchdown pass to Warfield. Morris racked up 33 rushing yards on the way to Miami's next first quarter touchdown, a 1-yard run by Csonka. In the second quarter, faced with 3rd and 1 from his own 44, Griese completed a 48-yard bomb to Warfield that set up Morris' 4-yard touchdown run. Miami's three touchdowns came on drives of 80, 80, and 73 yards, while all Cincinnati could manage in the first 26 minutes of the contest was 24-yard field goal by Horst Muhlmann on their first drive of the game. Even that drive caused a major setback for the team, as running back Essex Johnson, the team's leading rusher during the season with 997 yards, suffered a game-ending injury after picking up 14 yards on his first carry.

Facing the prospect of going into their locker room with a 21–3 deficit, the Bengals suddenly stormed back with 13 points in the final 3:26 of the second quarter. First, defensive back Neal Craig intercepted Griese's pass intended for Jim Mandich near the sideline and returned it 45 yards for a touchdown. Then the Bengals defense forced a punt and got the ball back on their own 33 with less than two minutes left. It took nearly all of that time for the team to cross midfield, but quarterback Ken Anderson finally got them into scoring range with a 22-yard scramble to the Dolphins 38, where Muhlmann made a 46-yard field goal that cut the score to 21–13. Now with just 8 seconds left until halftime, Morris fumbled the ensuing kickoff, and Bengals linebacker Jim LeClair recovered on the Dolphins 3-yard line. On the next play, Muhlmann kicked a 12-yard field goal that sent both teams into their locker rooms with a score of 21–16.

However, Cincinnati's hope of a comeback was quickly crushed in the second half. On the third play of the third quarter, Anderson tried to connect on a deep pass to tight end Bob Trumpy, but it was intercepted by Dick Anderson, who returned the ball 19 yards to the Bengals 28. Seven plays later, Miami went up 28–16 with Griese's 7-yard touchdown pass to Mandich. Dolphins kicker Garo Yepremian put the finishing touches on his team's victory with field goals from 50 and 46 yards.

This was the first postseason meeting between the Bengals and Dolphins.
