Chicago Bears running back David Montgomery suffered a leg injury in practice Wednesday and was carted off the field, according to ESPN's Adam Schefter.
Montgomery reportedly went to the ground in "serious pain" after slipping on the field.
Now in his second season in the NFL, the top tailback on the Bears' depth chart was expected to play a big role in the offense and help revitalize a rushing game that finished as the sixth-worst in the league last year.
Montgomery played all 16 games in 2019 and finished with 889 yards and six touchdowns on 242 attempts, good for 3.
