The good: Quarterback Mitch Trubisky will need a shoulder harness, and he’ll be in pain, but he is expected to return Sunday after a dislocated left shoulder forced him out of the loss to the Raiders in London.

The bad: The Saints are 4-0 with Teddy Bridgewater starting for injured Drew Brees at quarterback.

The ugly: Bears left tackle Charles Leno has been called for eight penalties, second most among NFL offensive linemen behind Broncos guard Ronald Leary (nine).

Offense: Run, Mitch, Run!

QB Mitch Trubisky has fewer rushing yards in four games (21) than he averaged per game last season (30.1). And he is still feeling the effects of a dislocated left shoulder suffered on Sept. 29. But should he run against the Saints and risk injury? Saints coach Sean Payton is expecting just that.

Before departing the Vikings game on Sept. 29, QB Mitch Trubisky tied Billy Wade as the third-fastest Bear to reach 6,000 career passing yards (30 games).

Kyle Long’s season — and maybe his career with the Bears — came to an end when the team placed him on injured reserve.

Defense: ‘D’ Goes on the Defensive

From defensive coordinator Chuck Pagano to many veteran players, the phrase was repeated almost as if being read from a script. That ugly showing in a 24-21 loss to the Raiders “was not us.”

LB Khalil Mack leads the Bears with 4.5 sacks this season and 53.5 since the start of 2015, tied for the second-most in the NFL with the Rams’ Aaron Donald and behind the Cardinals’ Chandler Jones (58.0).

Special Teams: Eddy Pineiro gets ready for fall

With a warm September giving way to cooler temperatures this month, Eddy Pineiro will practice at Soldier Field on Friday to get acclimated to the changing conditions, Bears special-teams coordinator Chris Tabor said Thursday. Fans will remember that Cody Parkey didn’t start practicing at the stadium last season until he began struggling on game days.

Did you know?

Pineiro, who wasn’t listed on this week’s injury report, also appears on track to take over the Bears’ kickoff duties again soon. Punter Pat O’Donnell has filled that role since Week 3 while the kicker deals with a pinched nerve in his knee.

has filled that role since Week 3 while the kicker deals with a pinched nerve in his knee. Only three NFL kickers have been perfect on multiple attempts from 50-plus yards this season: The Rams’ Greg Zuerlein, Bucs’ Matt Gay and Pineiro.

What They’re Saying

Saints running back Alvin Kamara (knee, ankle) and tight end Jared Cook (knee) both missed Thursday’s practice because of injuries. Quarterback Drew Brees also remains sidelined as he works back from a thumb injury.

(knee, ankle) and tight end (knee) both missed Thursday’s practice because of injuries. Quarterback also remains sidelined as he works back from a thumb injury. Saints coach Sean Payton says he expects full-time referees to be the norm in the NFL soon: “Ultimately, we’re going to be at some point dealing with full-time officials. I don’t know that half of our fans even realize most of these guys aren’t even full time. I think the game is sped up so much now and we got better angles of it all. Shoot, the video angles of each play ... the fans are more educated, so I think we’re headed in that direction.”
