ORCHARD PARK, N.Y. (AP) — Buffalo Bills defensive tackle Kyle Williams is retiring after completing his 13th season.

Williams announced his retirement at age 35 through the team Friday, saying Buffalo's season finale against Miami on Sunday will be his last game.

He says it wasn't an easy decision and there's no ideal time to retire, before adding: "It's time to hang up my cleats."

Williams is the team's most respected leader and longest-active tenured player. He was drafted out of LSU in the fifth round in 2006.

Williams briefly considered retiring after the 2016 season before returning to play after Buffalo hired coach Sean McDermott. He then signed a one-year contract this past March after the Bills reached the playoffs to end a 17-season drought.
