Players at the Pro Bowl have been warned to stay away from the club in which Redskins tackle Trent Williams was attacked Friday morning, according to a league source. Williams required stitches after the incident at "M Nightclub" in Honolulu. NFL Security made the recommendation "pending (the) outcome of a criminal investigation being conducted by the Honolulu Police." One male has been arrested for "Assault in the 3rd degree," Captain Andrew Lum of the Honolulu Police Department said in a statement. Three males were injured and two were treated and released from the hospital.
