Usik: "Fury has a biopolar disorder."

WBA, WBA, WBO and IBF heavyweight boxing champion Oleksandr Usyk commented on WBC belt holder Tyson Fury's remarks about him.

"Why did Fury started to speak respectfully about me? I believe that Tyson has bipolar disorder. A little bit... One week he's saying I'm a rabbit, I'm bad, welterweight, blah, blah, blah... The next week I'm a good boxer and a lot of good words about me. I don't think about it, my focus is on the fight," said Usik in an interview with YouTube channel The Stomping Ground.

Recall that the Ukrainian and the Briton will fight on May 18 in the main event of the evening of boxing in Riyadh, Saudi Arabia.
