Jairus Byrd is about to hit the free agent market, but his running mate, Aaron Williams, just signed a lucrative contract extension with the Buffalo Bills. The Buffalo Bills announced on Wednesday that they have signed fourth-year safety Aaron Williams to a contract extension. Mike Garafolo of FOX Sports 1 reports that it's a four-year deal worth $26 million, with another $1.25 million in incentives. Mike Florio of ProFootballTalk.com has the guaranteed figure at $14.625 million. The news comes on the heels of the Bills' decision not to use the franchise tag on Jairus Byrd, though team president Russ Brandon was quick to state that Buffalo's extension of Williams was separate from that decision.
