Alexander Krassyuk, promoter for WBO, IBF, IBO, WBA heavyweight champion Oleksandr Usyk, has lashed out over the stalled talks to finalize a potential undisputed showdown with WBC world champion Tyson Fury.

The fight was in deep negotiations for the last few weeks, for a showdown date of April 29 at Wembley Stadium in London.

However, Usyk and his handlers have accused Fury of making continuous demands after their side agreed to take a 70-30 monetary split in the Gypsy King's favor.

According to Krassyuk, the fight is currently a dead issue and they will pursue other avenues.

The first order of business is a mandatory defense against the WBA's 'regular' champion, Daniel Dubois.

The World Boxing Association had previously given Usyk until April 1 to finalize the fight with Fury - or he would be ordered to make the mandated obligation with Dubois.

“The fight is called off. The reason for that is it went too far. There was a feeling that after Usyk accepted 70-30, Tyson Fury started thinking that he could put a saddle around his neck and start riding Usyk as much as he can," Krassyuk explained to Talk Sport. 

“It’s not right. I mean, Usyk accepted the 70-30 split as a courtesy. He was so loyal and he was so willing to make this fight happen. But the fight isn’t about Tyson Fury, the fight is about the WBC belt that is pending in his collection.

“If I start telling you the list of things [Fury] wanted, one, five, ten, or 15 minutes will not be enough. There was a list of things he wanted to get in his favor that was absolutely unacceptable, which were completely disrespectful to the unified champion and former undisputed [cruiserweight] champion.

“I cannot disclose the negotiations, it’s part of the ethics. So, if I start to go into the details, it won’t look good. Maybe, if the other party would be willing to take the decision to disclose what were the things then we can talk about it. At this time, I cannot do this just for this reason…. With huge regret in my heart, I must admit [the fight is off]… [Usyk] will take a short break and comply with his mandatories.”
