Butler's next bout earned him infamy on November 23, 2001, at the Roseland Ballroom in Manhattan, New York. The bout was a charity event to benefit surviving New York firemen and police officers of the September 11, 2001 terrorist attacks in New York City and was televised live on ESPN2. Butler faced Richard "The Alien" Grant, a fighter who had decisioned him early in his career. After losing the rematch by unanimous decision, Butler had his gloves removed before the announcement of the winner, Grant then went to Butler's side of the ring for an expected exchange of congratulations. Instead, Butler sucker-punched Grant, nailing a bare-handed right hook to his jaw. Grant suffered a temporarily dislocated jaw and a lacerated tongue that required 26 stitches. Butler was arrested and charged with 2nd degree assault. Butler was later convicted and served four months at Rikers Island detention facility.
