"Yeah, they're talking right now," Williams told The Associated Press. Following the team's night practice on Wednesday, Williams added the discussions are not that far along, but didn't have any further details because his agent is handling talks.
General manager Buddy Nix declined comment, citing the team's policy of not discussing contract talks.
Williams has been a starter since his rookie season in 2006, when the Bills drafted him in the fifth round out of LSU. His current contract runs through the end of the 2012 season. And it's been extended once already, in 2008, when he signed a deal that was worth $14.4 million.
Though comparatively undersized among NFL defensive tackles, the 6-foot-1, 300-pound Williams has been the Bills most consistent and reliable defensive player. He's missed only two games, in 2009 due to a knee injury.
And he's coming off a solid season in which he had a career-high and team-leading 5½ sacks. That was good enough to earn his first Pro Bowl appearance despite playing on one of the NFL's worst defenses. He was selected as a first alternate and then added to the AFC team to replace injured Oakland Raiders lineman Richard Seymour.
Overall, he has 13½ sacks in 78 games.
"This is where I want to be," Williams said. "I feel like we've got a chance, and we're moving in the right direction. We've got some good players here, and I want to see what I've started here through."
