Buffalo Bills waive injured guard Keith Williams

In their latest in a recent string of roster moves, the Buffalo Bills waived reserve guard Keith Williams on Tuesday. They did so with the waived/injured designation, meaning that if he clears waivers, he'll wind up on the team's IR list, which is what happened with tight end Mike Caussin.

Williams had missed a long stretch of time in training camp - not to mention the team's first two preseason games - due to injury. Free agent signing Antoine Caldwell has been the main beneficiary; though he was added to the roster after camp began, he currently leads the team with 92 preseason game reps while working with the second and third-team offenses at right guard.

A former sixth-round pick of the Pittsburgh Steelers, if Williams does wind up on IR here, there's a good chance we'll see him next summer in training camp.

Buffalo now has 14 offensive linemen on the roster after the Williams move - and one of those, tackle Chris Hairston, remains on Active/PUP with a back issue that has kept him out of training camp entirely. Here's what the Bills' depth chart with healthy offensive linemen looks like heading into the final two weeks of the preseason.
