Alexander Krassyuk, the promoter for WBO, IBF, IBO, WBA heavyweight champion Oleksandr Usyk is still not convinced that a unification fight will take place with WBC champion Tyson Fury.

Last Friday, the World Boxing Association was informed that Fury and Usyk had reached a tentative agreement to collide on April 29 at Wembley Stadium.

The WBA was pressing both boxers to reach a deal - or the sanctioning body would have ordered Usyk to make a mandatory defense against Daniel Dubois.

Usyk accepted Fury's demand of a 70-30 monetary split - if Fury donates $1 million to Usyk's home country of Ukraine, which is currently engaged in a military conflict with Russia.

The Ukrainian boxer and his team are under the impression that Fury will still go in another direction.

According to Krassyuk, Usyk called Fury's bluff by accepting the proposal of a 70-30 monetary split. He says Fury is continuously making new demands, which Krassyuk feels is a tactical move to make the fight fall through.

"As Usyk said, the greedy belly (Fury) is still hoping to find a way to pull out. We knew before and know it now. As soon as Usyk accepts a no rematch clause there will still be searching for another thing to find and pull out the fight. I tell you why. He bluffed and Usyk called his bluff. This is 100 percent. He didn't expect Usyk to accept 70-30," Krassyuk told Talk Sport.

"It's all about nothing. He's not prepared and scared to fight. He will try to find a way to avoid Usyk for as long as possible. We don't trust him, we don't believe him. I don't believe anyone will fight. Even if you accept this now, he will still try to find a way out."
