"The greatest tight end in Buffalo Bills history has a deal to join coach Chan Gailey's staff.

Pete Metzelaars has agreed to fill the last opening on the Bills' coaching staff, a source close to the situation told The News. Bills great Jim Kelly, who strongly recommended Metzelaars to Gailey, tweeted the agreement. It's not expected the Bills will announce the move until a contract is signed.

Metzelaars, 51, spent the past two years as offensive line coach for the Indianapolis Colts. He lost his job on Jan. 17 when the Colts fired head coach Jim Caldwell. Metzelaars worked six years before that as offensive quality control coach for the Colts, and spent a lot of time learning under assistant coach Howard Mudd, one of the most veteran and respected offensive line coaches in the game.
