Cierre Wood

The Buffalo Bills entered Sunday's Week 5 game with just three active running backs. Unfortunately, they're now down to only two.

Cierre Wood was carted off the field in the second quarter against the Tennessee Titans with a knee injury and has been ruled out for the remainder of the game.

LeSean McCoy (hamstring) and Karlos Williams (concussion) are both dealing with injuries of their own and were forced to miss Sunday's game, leaving just Boobie Dixon and the recently-acquired Boom Herron as the only healthy backs.

It's unknown how severe Wood's injury is, but any time a player is carted off, it's possibly serious, the story pointed out. Although it's not always the case. While McCoy will likely be out through the team's Week 8 bye, Williams should return sooner rather than later. Herron carried 9 times for 28 yards and Dixon just seven times for 19 yards.
