Career
Prior to fighting, Guthrie was an admitted former player in the Street Louis drugs scene, and he had been kicked off the 1988 United States Olympic team after failing a drug test. He also later spent time in prison for drug possession. He was seen as a looming threat to Roy Jones Junior at light heavyweight due to his punching power, but instead of a unification bout, he lost the title in his next fight to Reggie Johnson by a knockout in the 5th.
The knockout was a brutal one, and Guthrie left the ring on a stretcher.
Instead of retiring, he instead moved up to cruiserweight and continued to fight, but has not fought for a belt since.
