There is still no agreement for the heavyweight clash between top contenders Oleksandr Usyk and Joe Joyce.

The World Boxing Organization has approved Usyk vs. Joyce to have the WBO's interim-heavyweight title at stake. The winner of their contest would have a mandatory world shot at the victor of the WBO/WBA/WBC/IBF/IBO unification clash between Tyson Fury and Anthony Joshua.

Earlier this week, it was revealed that Usyk and Joyce had signed their portions of a two-fight agreement - with a date and location being pursued by both sides.

Usyk recently took to social media to explain that he rejected an offer from Team Joyce and made a more lucrative counter.

"The offer was unsuitable, so we made a more viable counter-offer. Joyce shouldn't think too much of himself and fall in line with everyone else. I'll be the one making the final decision," Usyk stated.

But Joyce's promoter, Frank Warren, denied that a counter was ever received.

"We haven't received any counter offer from you or your team. We made an offer to your manager again last week. Joe wants this fight. We want this fight. It sounds like you want this fight. Let's get this made for the fans," Warren said.

Usyk's promoter Alexander Krassyuk previously explained to Sky Sports why his boxer deserved the majority of the money in such a fight.

"[WBO president] Paco Valcarcel is a very fair and reasonable man! But the purse split is a matter of mathematics not of anything else. The calculation is very simple. Three last declared purses of Usyk plus three last declared purses of Joyce equals the total pot. Usyk's purse divided to the total pot multiplied by 100 percent equals his percentage," Krassyuk said,
