Audley Harrison won a gold medal, Danny Williams ruined Mike Tyson, Scott Belshaw was knocked out by Tyson Fury in his last fight and tonight they will fight for the £32,000 prize and the Prizefighter Cup at the ExCel Arena in London's Docklands.
The mad and entertaining event will start at nine sharp with the first of four quarter-finals, followed by the semi-finals and then the final at about 11.45pm. All of the fights will be over the old-fashioned amateur distance of three rounds at three minutes for each round.
Harrison and Williams, who have met as professionals and have a win each, are the seasoned pair, but the event also has novice heavyweights Neil Perkins, who has fought just four times, and Danny Hughes, who is unbeaten in seven fights. Williams is also the British heavyweight champion and will lose his title, which will become vacant, if he fails to win all three of his fights.
Harrison meets Belfast's Belshaw, Williams meets Sheffield's enormous Carl "The Fridge" Baker, the former British champion Scott Gammer meets Galway's Coleman Barrett and the last quarter-final is between Perkins and Hughes.
A Williams versus Harrison grudge fight final is expected, but there will be a lot of fun before that happens.
