The Miami Dolphins shut out the Baltimore Colts 21-0 at Memorial Stadium in a rematch of the 1971 AFC Championship Game. The Colts, who won Super Bowl V, were a team in transition in 1972. They had new owners, and coach Don McCaffery was fired after a 1-4 start. At the same time, longtime quarterback Johnny Unitas was benched. Earl Morrall, who had backed up Unitas before joining the Dolphins, completed 9-of-15 passes for 86 yards. Larry Csonka had a pair of touchdowns while rushing for 93 yards on 19 carries, while Mercury Morris had 71 yards with a touchdown on 11 carries. The Dolphins rushed for 286 yards, improving to 7-0.
