Tyson Fury and Oleksandr Usyk's teams have told the World Boxing Association (WBA) they have reached an agreement for a heavyweight unification fight.

A proposed mouthwatering battle between WBC champion Fury and WBA-Super, IBF, WBO and IBO strap-holder Usyk has been shrouded in doubt as the two parties were unable to settle on terms.

Alex Krassyuk, Usyk's promoter, revealed Fury had rejected a 60-40 purse split in favour of the winner for a bout at Wembley on April 29.

Usyk then put the ball back in "greedy belly" Fury's court by agreeing to the Briton's demand for a 70-30 split, provided he immediately donates £1million to warn-torn Ukraine as they continued to do their talking over social media rather than around the table.

But the WBA later provided an encouraging update, stating assurances have been made that an agreement was reached ahead of Friday's deadline.

"WBA President Gilberto Mendoza received confirmation from Oleksandr Usyk and Tyson Fury's teams that there is an agreement to make the unification fight," the WBA tweeted. "They request time to work on the contracts to close the deal."
