Orchard Park, NY (SportsNetwork.com) - The Buffalo Bills have signed Pro Bowl defensive tackle Kyle Williams to a contract extension, the team announced Friday.

Williams, 31, will enter his 10th NFL season as the longest-tenured Bills player, having been drafted by the team in 2006.

He earned his fourth Pro Bowl nod, and second in a row, after posting 5 1/2 sacks, 41 tackles and his first career interception in 15 games last season. He missed a game for the first time since 2011 because of a knee injury.

Williams has 34 1/2 sacks -- the most ever by a Bills tackle -- and 456 tackles in 130 career games, including 125 starts.
