Two of the biggest and most dangerous fighters on the planet will meet in Saudi Arabia as boxing champion Tyson Fury takes on former UFC star Francis Ngannou in a fight dubbed ‘The Battle of the Baddest’.
The fight is expected to attract huge excitement and attention from fans of both sports and is an opportunity to settle the debate on how a UFC fighter would cope with the demands of professional boxing.
Ngannou in theory has many of the traits needed to succeed in the sport - he has phenomenal punch power and experience in competing at the top level of the sport.
But in practice it could prove to be a tricky challenge as he faces up to the task of taking on a fighter who has never been beaten in his professional career.
The crossover bout will attract huge intrigue from the sporting world, but it is not the first time a fighter from a different sport has tried their hand at boxing.
With that in mind we take a look at some of the biggest crossover fights in history and the outcomes of the bouts.
