Bills defensive lineman Kyle Williams announced he will retire after the season on Friday, writing a letter to the city of Buffalo after 13 seasons with the Bills.
"There's no perfect time to retire from a game, a franchise, and a city that mean so much to me and my family," Williams wrote in a statement. "But it's time to hang up my cleats."
The LSU product has spent his entire 13-year career with Buffalo, reaching the playoffs for the first time in 2017. Williams is a five-time Pro Bowler, totaling 48.5 sacks and 607 tackles since entering the league in 2006.
Williams has played 182 games for the Bills, seventh-most in franchise history. He will play his 183rd and final game on Sunday as Buffalo hosts Miami. Kickoff from New Era Field in Orchard Park, N.Y. is slated for 1 p.m. ET.
