Here's what we know about the Buffalo Bills' offensive line heading into their Week 14 showdown with the St. Louis Rams: it's beat up. Two starters, center Eric Wood and right tackle Chris Hairston, won't be playing thanks to their respective knee and foot injuries. Hairston will be replaced in the starting lineup by Sam Young, a third-year player out of Notre Dame.
We also know that David Snow, an undrafted rookie free agent out of Texas, will be starting on Sunday as well. We're just not yet sure precisely where he'll be playing.
For the last two seasons, right guard Kraig Urbik has acted as the top in-game backup to Wood. When Wood left last week's win over Jacksonville in the fourth quarter, Urbik slid over into the pivot as usual, and the 6'4", 305-pound Snow took over at right guard. It's easy to assume, then, that Urbik and Snow will pick up where they left off against the Rams - but we all know the saying about assumptions.
Joe Buscaglia of WGR 550 reports that both players took reps at center during the positional portions of Wednesday's practice - and that Snow worked there first. At a minimum, that indicates that the Bills are still mulling their options at center. It could also mean that the Bills are comfortable enough with Snow, a two-year full-time starting center at Texas, to let Urbik continue to play at right guard.
In short, Buffalo's five line starters are set at this point; we're just not sure if Snow will be at center and Urbik at right guard, or vice versa.
Aside from Wood and Hairston, the Bills had three other non-participants on Wednesday: wide receiver Stevie Johnson, defensive end Mark Anderson and defensive tackle Kyle Williams. Both Johnson and Williams are expected to return to practice on Thursday.
