Buffalo Bills running back LeSean McCoy will be a game-time to play in Week 15 against the Detroit Lions due to a hamstring injury, according to Ian Rapoport of NFL Network.

Rapoport adds that the Bills will also be without veteran running back Chris Ivory, who is dealing with a shoulder injury. If McCoy also can’t go, Keith Ford and Marcus Murphy would be the Bills’ two primary running backs.

McCoy suffered the injury in last week’s loss to the New York Jets. He left the game after just two rushes and did not return. He recently said he would “love” to return for the final games of the Bills’ season and add to that surprisingly low rushing total.

The 30-year-old McCoy has had a tough campaign with the Bills this season. In 12 games, he has rushed for just 479 yards, which would be his lowest total since his rookie season, on 3.3 yards per carry.

Despite McCoy leaving early against the Jets, the Bills were still able to rack up 176 rushing yards. That’s because of quarterback Josh Allen, who ran for an impressive 101 yards on nine carries with one touchdown.

Since returning from an elbow injury, Allen has done most of his damage with his legs instead of his arm. He has rushed for 335 yards on just 31 carries with two touchdowns in his last three games.

Allen will likely have to continue to churn out yards anyway he can with the threat of McCoy likely not around to deter the Lions defense.
