Buffalo Bills sign Billy Cundiff, Denarius Moore; release Jordan Gay, Marcus Thigpen

The Buffalo Bills continue to tweak their roster heading into a Week 5 matchup with the Tennessee Titans, signing free agent kicker Billy Cundiff and wide receiver Denarius Moore on Wednesday. To make room for the two new additions, the Bills released kickoff specialist Jordan Gay and punt returner Marcus Thigpen.

Cundiff is the more intriguing of the two signings. Bills head coach Rex Ryan has been public in his disappointment with kicker Dan Carpenter, who has missed two field goal tries and an extra point through the team's first four games. Cundiff is not better than Carpenter, but he does have a bigger leg, meaning that he'll give the Bills a capable kickoff option on game days, and perhaps a second option if Ryan doesn't trust Carpenter with a kick in-game.

Moore is a fifth-year player who hasn't been able to improve on solid 2011 and 2012 campaigns with the Oakland Raiders; those were his first two years in the league. Moore was released by Cincinnati (and the coach that gave him his start as a rookie, Hue Jackson) on August 31, just a few months after the team signed him in free agency. The 26-year-old has 142 career receptions for 2,169 yards and 17 touchdowns.

Gay and Thigpen held two of the more specialized roles on the team. Cundiff will probably assume kickoff duties, but the punt return gig is a little less clear, with Robert Woods looking like an early front-runner if the team doesn't want Moore to handle them.
