Justin Fields gets no calls. There have been three hits tonight alone that could've been flagged the way the league treats quarterbacks, and there have been a few throughout his time at QB.

Bears officially activated David Montgomery from IR for tonight's game vs. the Steelers.

Roquan Smith says "BS at the end of the day." #Bears unhappy about the way the game was officiated, no question about that.

Bears right guard James Daniels got called for a low block and he still missed the guy. You can't make this stuff up.

Sort of sums up 2021 offense. Opponent shanks a punt, #Bears start at own 48. First play is a rare explosive - 25 yards to Cole Kmet. And they wind up punting.

Cairo Santos has now made 40 FGs in a row, that ties for the third longest in NFL history with Gary Anderson (1997-1998).

I'd be curious what the officials would like Jaylon Johnson to do differently on that play while still playing defense.

68 receiving yards for Allen Robinson is a season high.

This is a sweet vet move by LT Jason Peters on the hard count. Opens his hand to try to get the DL to react to the movement. Looks like they were already jumping offsides but it's a little thing that OL can do to try to get the DL to jump. pic.twitter.com/I5Q2R1GfXk

#Bears rookie OL Teven Jenkins doing some stretching on the field under the watch of strength coach Jason Loscalzo. Have to imagine there is a chance, maybe a good one, the 21-day practice window for evaluation with him on the PUP list begins before the Baltimore game.

Jimmy Graham entered tonight with 3 targets on the season and they just called 2 end zone fades to him in a row??

Jakeem Grant fumbles the kickoff return and #Steelers recover. That's how bad goes to worse.

The Bears' defense doesn't have Khalil Mack, Eddie Jackson or Alec Ogletree. They're down to playing Sam Kamara and Cassius Marsh. And the Bears' offense is awful. I'd actually say that Sean Desai is doing a hell of a job tonight. It could be much worse than 14-0.

Referee Tony Corrente announces the call on the field stands. 50-yard shot play to Marquise Goodwin. #Bears at the PIT 14-yard line.

Jesse James, a captain for the Bears, gets a big hug from Roethlisberger and Heyward.

As we all expected, DeAndre Houston-Carson's fumble return touchdown on a punt keeps the Bears' hopes alive. Steelers 23, Bears 20

Mooney is the Bears’ leading receiver at 33 catches for 409 yards and a touchdown. | AP PhotosThe Bears will have Mooney and running back David Montgomery. On defense, though, they’ll be without outside linebacker Khalil Mack and safety Eddie Jackson. PITTSBURGH — The Bears will have two key offensive players tonight against the Steelers with running back David Montgomery returning from his sprained knee and wide receiver Darnell Mooney being active after a groin injury limited him in practice Friday and Saturday.Both are essential to the Bears’ offense. Mooney is their leading receiver at 33 catches for 409 yards and a touchdown, while Montgomery averaged 77.3 yards per game before exiting in Week 4.Here are the Bears’ inactives against the Steelers:QB Nick FolesRB Damien WilliamsTE J.P. HoltzOLB Khalil MackILB Alec OgletreeDB Artie BurnsS Eddie JacksonWithout Williams, who injured his knee last week, the Bears will rely on Montgomery and sixth-round pick Khalil Herbert to power the running game.Mack will miss his second consecutive game as the Bears give him time to rest a sprained foot that has been problematic most of the season. With the bye week coming up, Mack will go nearly a month without playing from the Oct. 24 game against the Buccaneers to the Nov. 21 game against the Ravens.Jackson hurt his hamstring on the second play of the Bears’ 33-22 loss to the 49ers last week and did not practice. Bears coach Matt Nagy listed him as doubtful on the final injury report.

They're playing "Return of the Mack" at Heinz Field. OLB Khalil Mack, of course, is injured and out tonight for the Bears.

Cassius Marsh with a coverage sack when the #Bears really needed it.

With Alec Ogletree out, we'll see a lot of Danny Trevathan tonight. He'll be OK against the run, but curious to see how often #Steelers try to attack him in the pass game.

Bears D does a nice job getting off the field quickly on opening drive of Q3. But a 20-yard swing on the first snap -- a 5-yard loss turned into a 15-yard Mario Edwards personal foul -- costs valuable field position for an offense with little margin for error.

Akiem Hicks calls tails. The coin says heads. The Steelers defer. The Bears will get the ball first.

Touchdown, Bears. Fumble recovery on a punt return goes for a score. FF- Caleb Johnson. TD -- DeAndre Houson-Carson. Steelers 23, Bears 20.

Reset the number of games in a row the Bears have gone without a personal foul penalty from 1 to 0 after Angelo Blackson got flagged. Fortunately for the Bears, it was offsetting.
