The trainer of Paul Williams has said the boxer has been paralyzed from the waist down after being involved in a motorcycle crash. George Peterson told the Associated Press that Williams is expected to have surgery Wednesday and has been listed in serious but stable condition Monday at an undisclosed hospital. He said the crash happened Sunday morning in Marietta after Williams tried to avoid another car trying to negotiate a curve. He said the motorcycle went up an embankment and he was thrown from the bike, severing his spinal cord after falling on his back and head.
