ORCHARD PARK, N.Y. � Defensive tackle Kyle Williams agreed to a contract extension with the Buffalo Bills today.

The two-year starter received a three-year contract extension through 2012 worth $14.5 million, according the NFL Network.

The Bills confirmed the contract extension but did not release the terms. Williams' agent, Albert Elias, did not immediately return a call from The Associated Press.

Williams had two years left on his existing contract and was scheduled to make a base salary of $445,000 this season. The Bills' fifth-round pick in the 2006 draft out of Louisiana State has two sacks, both coming last season, in 32 career games.

He is expected to compete with former first-round pick John McCargo for the starting job alongside newly acquired veteran Marcus Stroud this season.

The Bills are off until the opening of training camp on July 25.
