Bills general manager Buddy Nix says he wants to work out a contract extension for Fred Jackson and the running back's agent believes him. "Buddy Nix has been honest and consistent with us all along," agent Ron Raccuia told WGR-AM. "I'm confident talks will get started in the next couple of months."

After a late-season pickup in 2011, Tashard Choice has decided to re-sign with the Bills. Choice had 23 carries for 70 yards, while adding seven catches for 51 yards in six games with Buffalo. The Bills claimed him off waivers on Nov. 23 after starter Fred Jackson broke his right leg.

The Bills have signed Mark Anderson to a four-year, $27.5 million contract. Anderson's signing is another attempt by the Bills to upgrade their defensive line following last week's agreement with Mario Williams. Anderson had 10 sacks last season with the Patriots.

Having signed Mario Williams, the Bills are optimistic about the 2012 season. The $100 million contract the Bills gave Williams is the largest for a defensive player in NFL history. The team's owner, Ralph Wilson, 93, wants to see the team win sooner than later. "I'd like to see us make the playoffs and possibly the Super Bowl while I'm around," Wilson said. "I don't expect to be around that many years."

Mario Williams on Thursday agreed to a six-year deal with the Bills that's potentially worth $100M and includes $50M guaranteed, a league source told ESPN NFL Insider Adam Schefter. It's the richest deal for a defensive player in NFL history.

The Bills have met most of the conditions for a contract with Texans free-agent defensive end Mario Williams and are "close to a deal," a league source told ESPN NFL Insider Adam Schefter. One source said the Bills will "do the deal," but they still are trying to satisfy another condition that concerns Williams. An answer is expected "real soon."

The Bills were hoping to wrap up a contract with Mario Williams while the free agent visited the team on Tuesday night, but they were unsuccessful. Two sources claim that the defender will visit other teams. Williams was still in Buffalo on Wednesday morning.

Mario Williams, believed to be the top defender on the free agent market, is scheduled to meet with the Bills on Tuesday night. Williams has also been linked to the Bears and Jaguars. He is expected to command in the neighborhood of $45-50 million guaranteed, depending on the length of his contract.

The Bills have agreed to a two-year contract with Scott Chandler, keeping the tight end from free agency. "Reunited and it feels so good!!! Blessed to be back with the Bills!" Chandler wrote on his Twitter page. "Nowhere else I want to be!" The deal comes before Chandler was eligible to become an unrestricted free agent next week.

The Bills have signed Stevie Johnson to a five-year, $36.25 million contract extension. Johnson, who caught 76 passes for 1,004 yards in 2011, would have become a free agent next week. "I want to do all I can to make sure and let them know they didn't make a mistake," Johnson said. "I want to make sure they look good. This is where I started, and I wanted to remain loyal to them." "I'm fired up," Ryan Fitzpatrick said. "This shows a lot about Stevie, and this shows a lot about where the Bills are headed. Being our go-to guy in the receiving corps and being a huge playmaker for us, it was a must in terms of re-signing him."
