Chicago Bears running back David Montgomery will be sidelined two to four weeks with a groin injury, NFL Network’s Ian Rapoport reported Thursday.
That timeline gives the second-year player a shot at being ready for the scheduled Sept. 13 season opener against the Lions in Detroit.
Montgomery, 23, slipped and fell to the ground before taking a handoff from quarterback Mitchell Trubisky during Wednesday’s practice.
A third-round draft pick in 2019 out of Iowa State, Montgomery led the Bears with 242 carries for 889 yards and six touchdowns as a rookie. He also caught 25 passes for 185 yards and one score.
Chicago’s thin depth chart behind Montgomery includes Tarik Cohen and converted wide receiver Cordarrelle Patterson.
