Not a lot has gone right for the Chicago Bears so far this season, and now the team is expected to be without starting running back Jeremy Langford for a number of games.

According to a report from ESPN’s Adam Schefter, Langford is expected to miss four to six weeks with a sprained ankle, an injury suffered in the team’s 31-17 Sunday Night loss to the Dallas Cowboys.

Langford left the Cowboys’ AT&T Stadium in a walking boot Sunday.

Langford was replaced by third-string running back Jordan Howard Sunday with backup Ka’Deem Carey inactive with a hamstring injury. Howard finished with 45 rushing yards and 47 receiving yards.

It’s unclear yet whether Howard or Carey will get the start next week against the Detroit Lions.
