Chicago Bears running back Jeremy Langford is believed to have suffered a sprained ankle during Sunday's game against the Dallas Cowboys, a source told NFL Network's Ian Rapoport.
Langford was originally feared to have sustained an Achilles injury.
The second-year pro rushed for 31 yards on three carries prior to leaving the game, adding two receptions for 15 yards.
