Britain's Anthony Joshua faces Ukrainian boxer Wladimir Klitschko at London's Wembley Stadium at a sold-out event that is expected to match the British fight attendance record of 90,000. They have the IBF, IBO and WBA Super Heavyweight championships of the world in their sights.
Joshua, 27, has 18 knockouts from as many fights since turning pro in 2013, while Klitschko, 41, turned pro in 1996 and has 64 wins and four defeats.
The attendance record of 90,000 was set by light-heavyweights Len Harvey and Jock McAvoy at White City Stadium, London, in 1939.
The fight becomes the just the second boxing event to be staged at the national football stadium after Carl Froch knocked out George Groves in the pair's rematch in May 2014 in the packed stadium, according to the BBC, which notes that the fight set a post-World War II attendance record of 80,000.
