The Bears’ hopes for a perfect season were thwarted when Dan Marino and the Dolphins defeated the McMahon-less Bears on Monday Night Football, 38–24, and kept the '72 Dolphins the only undefeated regular season in league history (it wouldn't be until 2007 when the 2007 New England Patriots were able to tie this record). Miami struck first when Marino hit Nat Moore for a 33-yard touchdown. Bears backup Steve Fuller then threw a 69-yard pass to Willie Gault, and eventually snuck in for a 1-yard touchdown. After a Fuad Reveiz field goal to put Miami up 10–7, Marino hit Moore again that set up a Ron Davenport touchdown to increase the gap by 10 points. After the Bears scored on a Kevin Butler field goal, Marino hit Mark Duper on a crossing pattern for 52 yards. On 3rd and 7, he connected with Mark Clayton for 26 yards down to the Bears 1-yard line. Davenport then ran in, and the Dolphins led 24–10. Later, the Dolphins would increase their lead to 31–10. The Bears had not allowed 31 points in one half since the 1972 season opener. The Bears then scored in the third quarter, but any momentum they gained was lost when Butler muffed the ensuing kickoff, which Dolphins rookie Alex Moyer recovered at the Bears 46. Dan Hampton then tipped a Marino pass into the air, but it sailed downfield for 30 yards before landing in the hands of Clayton, who went into the end zone to make it 38–17. Fuller hit Ken Margerum for a 19-yard touchdown, but that would be the last score of the night for the Bears. Mike Singletary said in "America’s Game: 1985 Chicago Bears":
