Bills vs. Browns injury report, 2014 NFL Week 13: Chris Gragg out

The Buffalo Bills wrapped up three days' worth of practices in advance of Sunday's home game against the Cleveland Browns on Friday. Having not practiced at all this week, three players - defensive end Jarius Wynn, tight end Chris Gragg, and safety Bacarri Rambo - have been ruled out of the contest.

Wynn has not played (or practiced) since a Week 10 loss to Kansas City, during which he injured his knee. The Bills have been rolling with three defensive ends on the active roster in his absence.

Gragg was a non-factor as a rookie in 2013, but has carved himself a niche role on offense in his second season, as he's playing roughly 30 percent of snaps at this point in the season (and that's factoring in a game missed due to injury). He had even played 34 or more snaps in two of the last four weeks, so his absence will necessitate a schematic shift for the Bills, who use a lot of three-tight end looks - unless, of course, they're willing to give the recently-signed MarQueis Gray those snaps.

Rambo made his Bills debut last week, nabbing some garbage-time snaps on defense and playing 15 special teams snaps, as well. Without him in the fold, the Bills will be forced to play with just three safeties on the game day roster.

Two more players - wide receiver Robert Woods and kicker Dan Carpenter - are listed as probable with minor injuries. Both are expected to play.
