It's looking like the Buffalo Bills will field their third different starting left guard of the still-young 2014 season when they take on the New York Jets this Sunday: veteran Kraig Urbik worked in ahead of rookie Cyril Richardson with the first-team offense at the outset of practice on Wednesday.

Urbik had been the Bills' starting right guard from 2011-13, but lost his starting job this summer when the team moved his three-year cohort at right tackle, Erik Pears, inside to Urbik's guard position. Since then, he has been active every game day this season, serving as the primary interior backup, most crucially behind Eric Wood at center.

Richardson, a rookie out of Baylor, had started each of the Bills' last three games at left guard after free agent signing Chris Williams landed on IR with a back injury that had been bothering him since training camp. (Urbik saw 55 snaps at left guard in a Week 3 loss to San Diego filling in for Williams; Richardson leapfrogged him into the starting lineup the following weekend in Houston.)

The Bills have endured a revolving door at left guard for the last two seasons. In 2013, Colin Brown and Doug Legursky both started games at that spot; neither is with the organization any longer. Add in Williams, Richardson, and now apparently Urbik, and the Bills will have had five different starting left guards in their last 24 regular season games.

Buffalo's line, from left to right, looks like it'll be as follows on Sunday in New Jersey: Cordy Glenn, Urbik, Wood, Pears, and Seantrel Henderson.
