Pittsburgh Steelers running back Le’Veon Bell is out for the rest of the 2015 season due to a torn MCL. The Steelers will tap DeAngelo Williams as the replacement for the starting spot.

Bell, who already missed the first two games of the season due to league suspension, finished second in the NFL in yards from scrimmage last season and his absence for the rest of the year is a big blow for the Steelers, which is just 4-4 season.

The 23-year-old has played in five games for the Steelers this season, and is credited 511 rushing yards on 103 carries with 3 rushing touchdowns plus 123 receiving yards on 22 catches.

After starting 4-2 for the year, the Steelers have suffered back-to-back losses to the Kansas City Chiefs (23-13) and on Sunday, to the Cincinnati Bengals (16-10), in the game where Bell was injured. Bell twisted his knee when he was tackled in the second quarter and was carted off the field.

Bell’s injury is one of the many for Week 8 in the NFL. Elsewhere, Baltimore Ravens WR Steve Smith Sr. tore his Achilles, Miami Dolphins OLB Cameron Wake also ended up with an Achilles injury and both players are expected to miss the rest of the season.

Other players, who got hurt in NFL Week 8, include New York Jets QB Ryan Fitzpatrick (hand), Chicago Bears RB Matt Forte (knee) and San Francisco 49ers RB Reggie Bush (knee), among others.
