Regular season Week 1: vs. Buccaneers In the season opener against the Bucs, the Bears defense seemed lost for much of the first half of the game by allowing 28 points, and trailed 28–17 at halftime, but the offense was able to lead the Bears to a victory after
Jim McMahon scored 3 touchdowns, with
Matt Suhey scoring on another.
Leslie Frazier was also able to give the Bears defense their first highlight of the season by returning a
Steve DeBerg interception 29 yards for a touchdown on the second play of the third quarter. The Bears had allowed 212 yards in the first half, but eventually allowed only 95 in the second half.
Walter Payton had rushed for 120 yards on 17 carries, and McMahon completed 23/34 passes for 274 yards, two touchdowns and one interception.
Week 2: vs. Patriots In the Super Bowl XX preview, the Bears defense was able to find their groove by forcing 4 turnovers by New England and only allowing 7 points.
Week 3: at Vikings The following week against
rival Minnesota, backup quarterback
Steve Fuller was called up to take the place of
Jim McMahon, who was sidelined with a pinched nerve. With the Bears trailing the Vikings, an anxious McMahon was allowed to return to the game. Without any delay, McMahon famously spearheaded a Bears comeback and victory.
Week 4: vs. Redskins Week 4 saw Chicago trailing 10-0 early to the
Joe Theismann-led Washington Redskins. They would score the next forty-five points. One play turned the game, a 99-yard kickoff return by
Willie Gault. This cut the lead to 10-7 and importantly, on the play, Washington's punter injured his knee and was sidelined for the remainder of the game. On the next possession, Theismann punted for 1 yard (his only punt in the NFL), and Chicago scored on the very next play to take a 14–10 lead, and they cruised from there including
Walter Payton and
Jim McMahon exchanging touchdowns passes to one another.
Week 5: at Buccaneers After three second-quarter scoring drives by Tampa Bay, the Bears faced a 120 deficit.
Kevin Butler's 30-yard field goal got Chicago on the scoreboard before halftime.
Jim McMahon's 21-yard pass to
Dennis McKinnon opened the second half scoring, and
Walter Payton gave the Bears some breathing room with two fourth quarter touchdowns runs.
Week 6: at 49ers Nine months after their humiliating defeat at the hands of the 49ers in the NFC Championship Game, the Bears claimed their revenge by sacking
Joe Montana a then-career high seven times. In return for 49ers coach
Bill Walsh’s idea of sending lineman
Guy McIntyre in as fullback the season before,
Mike Ditka sent in rookie
William Perry, but as a runner rather than a blocker. This was the Bears’ last victory at
Candlestick Park, and their last win at San Francisco until 2014 at
Levi's Stadium.
Week 7: vs. Packers The Bears defeated the Packers on
Monday Night Football in a decisive 23–7 victory, with Perry becoming a folk hero after scoring his first career touchdown on a 1-yard run.
Week 8: vs. Vikings Walter Payton racked up 155 yards (rushing and receiving) and caught one of two TD passes
Jim McMahon threw on the day. The defense forced five turnovers, one of which was a pick-six by
Otis Wilson, as Chicago moved to 80.
Week 9: at Packers The Packers increased tensions in the
Bears-Packers rivalry after putting horse manure in the Bears locker room. However, the Bears had the last laugh against their hated rival, winning 16–10, and Perry scored his first career receiving touchdown along the way. Green Bay's
Mark Lee and
Ken Stills intensified the game after Lee sent Payton over a bench and Stills leveled
Matt Suhey. With the Bears in trouble and trailing 10–7 in the 4th quarter, a
Steve McMichael safety proved to be the key play that turned the game. This cut the lead to 10-9 and the Bears got the ball at midfield following the safety
free kick. On the ensuing drive,
Walter Payton sealed the victory with a 27-yard touchdown run, putting Chicago up for keeps 16–10.
Week 10: vs. Lions The Bears defeated the Lions 24–3, while
Walter Payton and
Matt Suhey ran for 105 and 102 yards, respectively. As of February 1, 2021, this was the last time the Bears had two 100-yard rushers in a game.
Week 11: at Cowboys In a
student vs
teacher matchup, the Bears shut out the Cowboys, handing them the worst loss in franchise history, as well as the first time they were shut out in
15 years. The win also gave the Bears the NFC Central division title.
Week 13: at Dolphins 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. The Dolphins' victory persevered their
1972 season as the only undefeated regular season in the NFL since the
AFL–NFL merger, a feat that would not be equaled until 2007 when the
2007 New England Patriots went undefeated through the regular season. 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'': The day after this loss, the Bears filmed the video for "
The Super Bowl Shuffle", a
Grammy Award-nominated and
Billboard charts #41 charting rap single that delivered over $300,000 to the Chicago Community Trust.
Week 14: vs. Colts The 121 Bears hosted the 310 Colts and were 20-point favorites in week 14. The Colts marched the ball 72 yards to the Chicago one-yard line on the first drive of the game. But on third and goal, Gary Fencik stuffed a pitch play for a five-yard loss and the Colts' kicker missed a 22-yard-field goal attempt wide left. Both teams struggled to a 3-3 halftime score as Indianapolis outgained Chicago in the half. Chicago finally pulled ahead on a 16-yard Walter Payton TD run near the end of the third quarter and held on for a 17–10 victory.
Week 15: at Jets A second quarter TD reception by tight end
Tim Wrightman and four field goals from
Kevin Butler were plenty to complement the Bears' defensive dominance.
Week 16: at Lions Chicago never trailed in their regular season finale and scored 31 second-half points. The game featured a hit on Lions quarterback
Joe Ferguson where he was knocked unconscious by Bears linebacker
Wilber Marshall. ==Standings==
