The undercard has been set for the May 18 heavyweight unification clash between Tyson Fury and Oleksandr Usyk in Saudi Arabia.

Fury-Usyk was due to happen in February, until Fury was cut in sparring with the fight drawing near, and the show was postponed. 

Along with the main event fight, the cruiserweight rematch for the vacant IBF belt between former champions Jai Opetaia, of Australia, and Latvia’s Mairis Briedis retains its slot on the card.

There is also a colorful heavyweight clash of 24-0 prospects Frank Sanchez and Agit Kabayel. Miami-based Cuban Sanchez has stopped 17 of his 24 victims, while German Kabayel has halted 16 of 24.

Frank Warren’s young heavyweight prospect Moses Itauma is back in action, with the 8-0 prospect paired with 24-3 (20 KOs) Ilja Mezencev.

At cruiserweight, 12-0 (10 KOs) German Michael Seitz meets 8-0 (7 KOs) New Zealander David Nyika and Fury’s featherweight stablemate Isaac Lowe, 24-2-3, goes in against 16-1 Dubai-based Afghan Hasibullah Ahmadi.

Former light heavyweight champion Sergey Kovalev, 35-4-1 (29 KOs), is set for his first fight in two years when he meets 16-0 (12 KOs) Las Vegas-based Swede Robin Sirwan Safar.

Popular Portsmouth, U.K., fighter Mark Chamberlain, who stopped Gavin Gwynne in Saudi Arabia earlier this month, heads back to the Kingdom where the 15-0 (11 KOs) lightweight contender is up against 23-1 (16 KOs) Nigerian Joshua Oluwaseun Wahab.

The show is rounded off by IBF super featherweight champion Joe Cordina meeting Irishman Anthony Cacace, in another bout that was rescheduled from the original date. 

The champion Cordina, from Wales, is 17-0 (9 KOs), while Cacace is 21-1 (7 KOs).
