MMQB: Bears drop fourth straight

Justin Fields capped off the most impressive drive of his short career with a go-ahead fourth quarter touchdown throw to Darnell Mooney, but Chicago's defense ultimately couldn't hold off the Pittsburgh Steelers on Monday Night Football.

• The 29-27 loss was marred by 12 Chicago penalties, including a questionable taunting call late.

Why it matters: The Bears have now lost four in a row after starting the season 3-2.

Play of the game: DeAndre Houston-Carson scooping up a fumble on a punt and returning it 25 yards for a momentum-shifting touchdown in the fourth.

Justin Fields: The quarterback showed flashes, like a beautiful 50-yard bomb to Marquise Goodwin, against a tough Steelers defense. He also threw a terrible interception directly into the hands of a Pittsburgh lineman.

• So it goes with a rookie. Fields finished with 291 passing yards and another 45 yards on the ground.

MVP(s): Despite missing Khalil Mack, the defensive line kept the Bears in this game. The Steelers dominated time of possession but averaged just 3.2 yards per carry.

LVP: Recently acquired wide receiver Jakeem Grant fumbled a kickoff and made several questionable special teams decisions.

What's next: The Bears limp into their bye week needing a hard regroup. They take on the Ravens in Week 11.
