Pittsburgh Steelers running back Le’Veon Bell has suffered a torn MCL and has been informed that his season is over, a source close to Bell tells Steelers Depot.

It is uncertain if he suffered damage to his ACL but the injury to his MCL is enough to keep him out for the season. He suffered the injury in Sunday’s loss to the Cincinnati Bengals after a Vontaze Burfict tackle mid-way through the second quarter.

If his season is over, Bell will have finished his 2015 campaign with 511 yards rushing and three touchdowns to go with 22 receptions. Despite missing the first two games of the year after his suspension, he came into Sunday leading the AFC in rushing yards.

This is the second time playing against the Bengals that Bell has had his season end because of an injury. Reggie Nelson injured Bell’s knee in Week 17 last season, forcing the running back to sit out the Wildcard game against the Baltimore Ravens.

DeAngelo Williams will be the starter with now Bell out. Jordan Todman appears slated to be Williams’ backup.
