Chicago Bears running back David Montgomery is expected to miss four-to-five weeks after the knee injury he suffered Sunday against the Detroit Lions has been diagnosed as a sprain, according to ESPN's Dan Graziano.
The 24-year-old had to be helped off the field in Chicago's Week 4 win over the Lions after suffering the left knee injury late in the game.
Entering the 2021 season, the Iowa State product was projected to be the focal point of the Bears offense, with head coach Matt Nagy saying he intended giving him 20 carries per game.
