The Bills placed Cierre Wood on injured reserve Monday after suffering an ACL injury in Sunday's 14-13 win over the Tennessee Titans, and top backs LeSean McCoy (hamstring) and Karlos Williams (concussion) are still uncertain for this Sunday's game against the Cincinnati Bengals.
Williams remains in the NFL's concussion protocol while McCoy said last Friday that he was given a three-to-four week timetable after suffering a Grade 2 hamstring pull in Week 3.
Asked Monday if the Bills would add another running back this week, coach Rex Ryan responded, "I don’t believe we’ll have to do that about running back. I’m not sure. You know I don’t think we’ll have to do that but we’ll definitely look at and evaluate where we are with that situation."
So would they go into Sunday's game with just Dixon and Herron active?
"Well you still have [fullback Jerome] Felton too," Ryan retorted. "So, alright ... you have two running backs."
The Bengals' run defense ranks 17th this season, allowing 108 yards per game, but the Bills' rushing attack didn't fare much better in Week 5, as Dixon gained just 17 yards on seven carries while Herron added 28 yards on nine carries.
"Boobie is not what we want him to be right now because he had missed all of training camp," Ryan said. "I think he’d be the first to tell you that. So we’re doing the best we can, it’s just not an ideal situation."
Asked about his calf after Sunday's game, Dixon responded, "I'm better. I'm not gonna make that excuse. I know I won't be 100 percent this year. It's all about grinding and staying in the fight long enough to make plays and help your team win. That's what I did today, so I'm not worried about getting back to 100 percent. I'm just worried about winning."
Dixon is averaging just 1.3 yards per carry this season. He led Bills rushers with 38 snaps in the game, followed by Herron (14 snaps) and Wood (two snaps before his season-ending knee injury).
