Oleksandr Usyk to fight Fabio Wardley vs Daniel Dubois winner, then Tyson Fury| 'We're up for that!' says Frank Warren

Promoter Frank Warren intends to open negotiations for Oleksandr Usyk to fight the winner of Fabio Wardley's world title clash with Daniel Dubois.

Usyk, the unified heavyweight world champion, with wins over Tyson Fury and Anthony Joshua has proved himself the best in the division. Although he is now 39 years old, Usyk still plans on fighting three more times.

Next the Ukrainian will box Rico Verhoeven, a kickboxing superstar, on May 23. After that Usyk wants to fight the Wardley-Dubois winner and then have a trilogy bout with his great rival Tyson Fury.

For Usyk, who also holds the WBA and IBF championships, to retain his WBC title, he would have to defend against WBC Interim belt-holder Agit Kabayel.

Wardley and Dubois fight for the WBO heavyweight world championship on May 9 in Manchester and their promoter Frank Warren is open for the winner to box Usyk in a unification.
