Frank Warren hits out at 'bulls***' claims after Tyson Fury accused of breaking rules against Oleksandr Usyk

Frank Warren has hit out at 'bullsh*t' claims after Tyson Fury was accused of breaking the rules in his fight against Oleksandr Usyk.

Fury suffered a unanimous decision defeat to Usyk in Saturday's rematch in Riyadh, Saudi Arabia.

The scoring angered the Brit, who slammed the verdict in new backstage footage.

His long-time promoter Warren also made his feelings clear as he gave an astonishing post-fight interview in the ring, with the scorecards in his hands.

A couple of days removed from the world championship showdown, Warren has launched an outburst at claims Fury broke the rules before the bout.

Boxing fans had accused the self-proclaimed 'Gypsy King' of having his shorts pulled up too high for his bout against Usyk.

But the 72-year-old has jumped to Fury's defence, passionately refuting the suggestion that his fighter's kit was illegal.

"One of the journalists talking about him wearing his shorts up to underneath his nipples... bullsh*t is it," he told Box Nation.

"The referee came in the dressing room before the fight. The way he wore them was legal. Did you hear one complaint about that from the other side?

"None at all... some idiot in there who knows nothing about boxing coming out with that and it's just, I don't know, I just find it ridiculous some of this stuff."

Warren also shared his thoughts on Fury's beard, which came under scrutiny ahead of his rematch.

But the legendary promoter described the situation a 'non-issue' in yet another rant.

"A non-issue," he replied when asked about Fury's beard. "A total lot of crap and a non-issue. If it was illegal, then they wouldn't have allowed him to wear his beard.

"How many fighters you seen get in the ring with beards?!"
