CHICAGO -- Bears running back David Montgomery sustained a left knee injury in Sunday's win over the Detroit Lions, which was 24-14.

Matt Nagy, Bears coach, said that they would work through the severity of Montgomery's injury in the following days.

Montgomery ran left guard at the 11:10 mark in the fourth quarter for a five yard gain, but he stayed on the ground and felt obvious pain.

Darnell Mooney, Bears receiver, said that "as soon as he was tackled, and I saw his facial expressions and heard him, and then I was waving to the trainers to get over as quickly as possible."

Montgomery was finally helped off the field, and was immediately taken back into the locker room. The Bears then ruled Montgomery out for the rest of the afternoon.

Justin Fields, Bears quarterback, said that David is a leader. He's one the team captains. Before every game, he talks to us. He's a dog. He brings the same energy to practice and games every day. It's not serious, and I wish it was. You know what? Even if it's serious, he'll still be a leader and continue to lead this offense every day.

Montgomery had a productive day (106 yards rushing, two touchdowns) before the injury.

Montgomery leads the Bears in rushing yards with 309 and three touchdowns for the season.

Akiem Hicks, Bears defensive player, was injured in the groin during Chicago's first defensive play. He did not return to practice. A quad injury also occurred to Montgomery's backup, veteran Damien Williams.
