After 308 fights as an amateur, of which he won 256, he turned professional in 1997. Less than a year later on 24 October 1998, he won the IBF super middleweight championship from Charles Brewer via a disputed decision victory. After this he made 16 successful defenses of his IBF title against fighters such as Thomas Tate (twice), Glen Johnson, Silvio Branco, James Butler, Anthony Mundine, Charles Brewer in a rematch, and a controversial points win against Robin Reid. He was at the peak of his career when he won the WBA title on 13 March 2003 against WBA champion Byron Mitchell, winning by split points decision.
