Oleksandr Usyk will defend his WBC heavyweight title against former kickboxing champion Rico Verhoeven on 23 May at the Pyramids of Giza in Egypt.
The two-time undisputed heavyweight champion will return to the ring for the first time since his knockout victory over Daniel Dubois at Wembley in July last year.
Verhoeven will get the chance to fight for the title in just his second boxing match and his first since April 2014, when he beat Janos Finfera.
Usyk, who holds the WBA, WBC and IBF belts, said in a statement: "I truly respect people who reach the very top in their sport. Rico is one of them – a powerful athlete and a great champion. Being a champion isn't just about belts. It’s about years of hard work, discipline, and belief.
"I respect his journey – he’s truly the 'King of Kickboxing’. But this is boxing – a different game, with its own rules and its own kings. I’m ready and really looking forward to meeting him in the ring."
