THURSDAY, 10:02am: Montgomery will be out of action for 2-4 weeks, which means he still has a chance at playing in the Bears’ season opener against the Lions (Twitter link via NFL.com’s Ian Rapoport).
WEDNESDAY, 12:53pm: Bears running back David Montgomery went down with a non-contact injury on Wednesday, as Adam Schefter of ESPN.com tweets. After hobbling off of the field, the 23-year-old was diagnosed with a groin strain. Now, the Bears are awaiting word and hoping for the best. 
It’ll take at least a day or two to determine Montgomery’s timetable for recovery, but it’s possible that the Bears won’t have the young rusher for the start of the season. Without Montgomery, the Bears will have to lean even more on Tarik Cohen, plus support from Ryan Nall and Artavis Pierce. Cohen, of course, is utilized more as a pass-catcher than a traditional RB. Last year, he carried the ball just 64 times for 213 yards in total while recording a career-high 79 catches. Montgomery, meanwhile, logged 242 totes for 889 yards as a rookie.
This year, the Bears were counting on Montgomery to take a big step forward. The youngster has been eager to show what he can do, especially since cleaning up his diet.
“Whenever I had the craving for a Krispy Creme doughnut, I’d definitely go have one back in the day,” Montgomery said, via the team’s website. “But now, I fight the urge to go have one…I feel amazing. Everything feels good right now, as far as my body. I’m not as sore as I was last year because of the lack of food that I don’t need that has a lot of inflammation to it. And just running. Just being able to run and feeling good at how I run and being able to make the right cuts.”
I guess Tarik Cohen is gonna start
Cohen can’t handle #1 RB duties. He can’t consistently run between the tackles and Nall is just too unproven.
The Bears will be ok for one game with Cohen in the backfield ! But better as a special play back I can’t wait to see that big ol’e Patterson back there first game not just trick plays
Is this the opening stages of a potential Devonta Freeman signing???
Devonta Freeman has entered the chat.
The Bears should wait until experts determine the severity of the injury before making any frivolous moves. If the malady cuts deep into the season, I would still explore a trade before signing Freeman. Devonta simply isn’t worth over $5 million/season with his injury history. Some possible trade partners include New England, Pittsburgh, Detroit, and Baltimore. Those teams have a surplus at the position and I bet a young runningback could be acquired for a fraction of the cost (4th or 5th rounder)
Not sure why you think Baltimore has a surplus of RB talent. It was well hidden in the playoffs against the Titans and forced Lamar to carry too much of a load. Trade wise I think Kareem Hunt is the most intriguing possibility as he and Nagy have some history.
Ingram, Dobbins, Hill, and Edwards is plenty of depth. One playoff game is not a legitimate sample size. For goodness sakes, Baltimore broke the single season record for rushing yards!
He would cost to much by his recent contract
Detroit would never trade a RB to the bears. Plus they play in week 1.
