The Bills’ best chance to be competitive this year just limped into the locker room.

Via Mike Rodak of ESPN.com, Bills running back LeSean McCoy was just helped to the locker room by athletic trainers after suffering an apparent left leg injury in practice.

The Bills have been hit hard at a number of positions during training camp, but they’re getting really thin at running back.

But beyond sheer numbers, it would be hard to miss McCoy for any amount of time. They’re building a revolutionary offense-without-a-quarterback, and McCoy is going to be the centerpiece of it.

He wasn’t carted off, which may be a good sign. But it’s reasonable for the Bills to worry when such a large part of their plan has a problem.
