Lynch suffers shoulder injury

The Buffalo Bills' decision to go with only two running backs could hurt them badly.

Two weeks ago, the Bills cut third running back Xavier Omon to make room on their roster for receiver James Hardy, who was activated off the physically unable to perform list.

That move gave the Bills nine receivers and left them with Marshawn Lynch and Fred Jackson as the only viable backfield options. Fullback Corey McIntyre doesn't carry the ball.

Lynch hurt his shoulder in the second quarter of Sunday's game against the Jacksonville Jaguars. The injury was bad enough he was carted off the field. Lynch fumbled on the play.

Making the Bills' roster decision even more mystifying is they've scratched Hardy for each of the two games he was eligible to play. Hardy suffered a knee injury late last season.
