Haye started his ambition and passion for boxing at old-school boxing gym Fitzroy Lodge Boxing Club, where he quickly impressed and confidently won his first amateur bouts.
At the 2001 World Amateur Boxing Championships in Belfast, Northern Ireland he fought in the heavyweight 201 lb division where he beat world class Sebastian Köber to reach the final where he gave Cuban Odlanier Solís a standing eight before getting stopped by TKO (round 3) and taking the silver medal.
Based in Bermondsey, London, England, Haye turned professional in December 2002. Haye KO's his first 10 opponents before dispatching ex-World cruiserweight champion "King" Arthur Williams in five rounds.
In 2004, Haye met 40-year-old ex-WBO champion Carl Thompson for the IBO Cruiserweight Championship. In the fifth round, Thompson started to throw punches as he just tried to defend himself. With 7 seconds left in the round, Thompson landed two jabs followed by a straight right that knocked Haye out.
Despite losing his first title shot, Haye racked-up several wins before fighting Jean-Marc Mormeck for the WBA and WBC Cruiserweight Championships in November 2007. Haye defeated Mormeck with a TKO in the 7th round, despite being knocked down by Mormeck in the 4th. The victory confirmed Haye's arrival as a genuine world class fighter because Mormeck was ranked number one by The Ring magazine.
Multi-Belt Cruiserweight Champion
Before joining the Heavyweight division, Haye became the lineal cruiserweight champion as he held the WBA, WBC, WBO and The Ring Magazine after defeating then WBO Champion Enzo Maccarinelli in March 2008.
Move to Heavyweight
Haye has described the victory over Maccarinelli as "the final piece" in his cruiserweight jigsaw. Haye then moved to heavyweight and fought journeyman/contender Monte "Two Gunz" Barrett at The O2 Arena in London on 15 November 2008, winning via TKO in the fifth round. A year later, Haye met WBA champion Nikolay Valuev and, in a reserved display of accuracy and efficiency, defeated him via a majority decision to win a share of the heavyweight title.
In April 2010, Haye defeated former heavyweight belt-holder John Ruiz in his first WBA title defense via ninth round TKO after knocking him down four times during the fight.
After the fight, Haye immediately called on both Klitschko brothers, after claiming their recent challengers Eddie Chambers and Chris Arreola were "a disgrace to boxing."
On 13 November 2010, Haye defeated an overmatched Harrison via third round by TKO. Southpaw Harrison landed one jab during the entire fight. He staggered to his feet after being knocked down, only for Haye to immediately pounce right back on him, hitting him with another flurry of punches. The referee intervened and ended the bout.
Haye is the first British boxer to win a world heavyweight title since Lennox Lewis, and only the sixth Briton in history to win the title after Lewis, Bob Fitzsimmons, former WBC champion Frank Bruno, Herbie Hide (WBO) and Henry Akinwande (WBO).
Haye is the first and currently only boxer in the history of the sport to be seven stone or more lighter than an opponent in a World title fight and still come out victorious.

(About Nicolay Valuev) "He is the ugliest thing I have ever seen. I have watched Lord of the Rings and films with strange looking people, but for a human being to look like he does is pretty shocking."
