Buffalo Bills defensive end Mario Williams
underwent a procedure to address a nagging left wrist injury.
Bills coach Chan Gailey said Wednesday that Williams, one of the club's
marquee free-agent additions, had surgery to relieve discomfort in the wrist
and expected him to be a participant in practice next week.
The Bills have their bye this week.
Williams has totaled 16 tackles and 3 1/2 sacks while starting all seven games
