His manager, George Peterson, said the boxer was paralyzed and has no movement from the waist down after Sunday’s crash in Marietta, northwest of Atlanta.
Peterson said the 30-year-old athlete severed his spinal cord after falling on his back and head when he was thrown from his motorcycle.
Marietta police said in a statement Tuesday morning that Williams was driving at a high rate of speed which was too fast for conditions. Police say he could not negotiate a curve, and the bike slammed into the embankment.
Williams, a fighter known as “The Punisher,” is from Aiken, S.C. He was in metro Atlanta to attend his brother’s wedding.
