The Bears' Cairo Santos kicked a 47-yard field goal on the final snap of the half to cut the Steelers' halftime lead to 21-17.
The Bears took the lead on their first possession of the second half. A holding call on Steelers punt-gunner Skowronek negated a 54-yard net punt. Instead of the Bears taking over at their own 10, a re-punt gave them the ball at their 40. Williams' passes of 17, 14, and 14 yards set up a third-and-6, 25-yard touchdown pass to Moore. It gave the Bears a 24-21 lead with 8:29 left in the third quarter.
The Bears scored again early in the fourth quarter. A strip sack of Rudolph, by Sweat, was recovered by Sweat at the Chicago 46. The Bears moved 54 yards in 9 plays for a 2-yard Kyle Monangai touchdown run that gave them a 31-21 lead with 14:14 left.
The Steelers followed by driving 73 yards in 17 plays for a touchdown, a 3-yard Rudolph play-action pass to Pat Freiermuth on third down. The score cut the Bears' lead to 31-28 with 6:27 left. The longest play of the drive was a 19-yard reception by Calvin Austin on a third-and-6.
The Steelers got the ball back twice. They punted the first time, and after stopping the Bears in 24 seconds, got the ball back with 1:29 remaining. A 14-yard pass to Freiermuth opened the possession, but the Steelers were stopped just across midfield on the batted pass by strong safety Jaquan Brisker at the line of scrimmage.
The Bears kneeled down on the next snap to improve to 8-3 on the season.
The Steelers had more first downs (22-19), better third-down conversion percentage (57-54), more rushing yards (186-99), more sacks (2-1), fewer penalties and yardage (6/41-7/83), the same number of turnovers (2-2), and more time of possession (33:09-26:51), but couldn't secure the win.
Individually, Gainwell led all rushers with 92 yards on 10 carries. Rudolph – starting in place of injured quarterback Aaron Rodgers – completed 24 of 31 passes for 171 yards with 1-1 TD-INT for a passer rating of 86.9.
Tomlin said after the game he expects Rodgers to start next week at home against the Buffalo Bills.
