Bears place RB David Montgomery on IR, activate LB Danny Trevathan

The Bears placed David Montgomery on IR, where his window to return is 3-5 weeks. Akiem Hicks has also been downgraded to out for Week 5.

The Chicago Bears have officially placed running back David Montgomery on injured reserve, the team announced Saturday.

Montgomery suffered a knee sprain in last Sunday’s win over the Detroit Lions, where he’s expected to be sidelined 3-5 weeks, according to NFL Network’s Ian Rapoport.

Linebacker Danny Trevathan has been activated off IR following a four-week hiatus with a knee injury. Alec Ogletree has been filling in for Trevathan opposite Roquan Smith, and he did a solid job of it. It wouldn’t be a surprise to see Ogletree continue to start opposite Smith given his performance in the first four weeks.

Defensive tackle Akiem Hicks has been downgraded to out for Sunday’s game against the Raiders. Hicks suffered a groin injury on his first play in last Sunday’s win against Detroit.

The Bears elevated running back Ryan Nall to the 53-man roster from the practice squad, where he’ll serve as depth for running backs Damien Williams and Khalil Herbert.
