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."
