Derek Chisora will meet Deontay Wilder on April 4 at London's O2 Arena in what will be a 50th professional fight for both heavyweights.
Chisora, a cult hero in British boxing, has been a fixture at the top of the division for the last 15 years.
He has fought a litany of the finest boxers in the world, including Tyson Fury (three times), Oleksandr Usyk, Vitali Klitschko and many more.
Chisora has challenged for world titles twice before, headlined a football stadium in his third fight with Fury, and is on a run of good form.
America's Wilder has been widely regarded as the heaviest puncher in the sport and arguably one of the hardest hitters of all-time.
The former WBC heavyweight champion was unbeaten in 43 fights, a run that the Olympic bronze medallist began in 2008 and extended right up until his second fight with Fury in 2020.
With an knockout ratio of over 97 per cent, Wilder has scored some spectacular finishes along the way. After losing to Joseph Parker and Zhilei Zhang, Wilder rebuilt with a win over Tyrrel Anthony Herndon last year.
Wilder has been linked to a mooted contest with reigning unified heavyweight champion Usyk, but first will return to the UK for the first time since blasting through Audley Harrison in 2013, to fight Chisora.
