With three open roster spots, the Bills went to work to address their beat up front seven. Kevin Reddick was signed by the Bills to provide depth at linebacker. Reddick played for Buffalo during the preseason and spent time this season on Buffalo's practice squad. Reddick already has some knowledge of Rex Ryan's defense which will help him if he's called into action on Sunday.
In addition to Reddick, Buffalo signed two players off of practice squads. T.J. Barnes, a 6'7," 364 pound defensive tackle, was signed off of the NY Jets' practice squad. Barnes has appeared in six games with the Jets this season but was on the team's practice squad due to their talent and depth along the defensive line. Barnes seems like a good fit for Ryan's defense as he has the size to play nose tackle and he has familiarity with Ryan's system.
Last, Buffalo signed defensive end Lavar Edwards off of Dallas' practice squad. Edwards has spent time with Dallas, Oakland (practice squad) and Chicago this season.
