David Deron Haye (born 13 October 1980) is a British professional boxer from England.

Haye is the former WBA heavyweight champion. He is also the former unified world cruiserweight champion, holding the WBA, WBC, WBO, and The Ring cruiserweight titles, and the former European cruiserweight champion.

Haye started his ambition and passion for boxing at old-school boxing gym Fitzroy Lodge Boxing Club in Lambeth, South London, where he quickly impressed and confidently won his first amateur bouts.

In 1999, 18-year-old Haye participated at the world amateur championships in Houston, Texas, USA at light-heavyweight but was eliminated by experienced American Michael Simms early in the contest.

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 Odlanier Solís a standing eight count before being stopped by the Cuban in round three, and taking the silver medal.

Enzo Maccarinelli (born 20 August 1980 in Swansea, Wales) is a Welsh professional boxer who has fought at Cruiserweight and light heavyweight. He is a former World Boxing Organization (WBO) cruiserweight title holder and also held the European title at that weight limit. He is promoted by Frank Warren.

On 12 May 2000, Maccarinelli suffered his first defeat at the hands of southpaw Lee Swaby. Swaby, from Lincoln, England, sent Maccarinelli down with a crushing right hand, knocking Maccarinelli down in the third round. Maccarinelli never took the rematch against Swaby.

On 28 June 2003, Maccarinelli, known as "the Big Mac" won the vacant WBU cruiserweight title when he defeated Bruce Scott by fourth-round TKO. He made seven successful defences of his WBU title before vacating.

On 8 July 2006, Maccarinelli fought against former World Boxing Council (WBC) cruiserweight champion Marcelo Fabian Domínguez for the WBO interim cruiserweight title. Maccarinelli won the title with a ninth-round TKO.The natural progression was a title fight against the then WBO title holder, Johnny Nelson. Due to several injuries to Nelson this matchup never transpired, and On 22 September 2006 he announced his retirement, automatically relinquishing the belt and allowing Maccarinelli to be promoted to full champion status.
