Tyson Fury claims he would weigh career-heaviest 21 STONE in crossover fight with UFC champ Francis Ngannou

TYSON FURY said he would be weighing a career-heaviest 21STONE against UFC heavyweight Francis Ngannou.

For the past few years, the champions of boxing as well as the UFC have been fighting each other. This has fueled talk about a cross-over fight.

Fury has recently laid out a plan for retirement after Dillian Whyte's title defense on April 23. However, it wouldn't affect Ngannou's'special fight.

The Gypsy King would put on the weight for a bout according to boxing rules, but in a cage that had the smaller 4oz gloves.

Fury stated on the MMA Hour, "We have Francis Ngannou. He's a big man, a dangerous guy."

"I would love to see people saying, "Oh, it's no fair fight in 10oz gloves," and that's true.

"It wouldn’t be fair to fight in 10oz gloves, because, like [Daniel] Cormier recently said, Francis Ngannou was a cruder version Deontay Wilder and we all know what happened there.

"So, I believe that if we were using four-ounce gloves, he would have a better chance of knocking us out. But then again, I'd also have a greater chance of knocking him out.

It makes for an exciting fight. For that fight, I will be at my heaviest.

"I'll try and come in over 300 lbs - just so he can be nailed to the canvas with one punch."

Fury, 33 years old, is calling to fight Ngannou (35), in Las Vegas next year, but Fury first returns to the UK for a homecoming at Wembley Stadium.

After promising to take the undisputed crown in the Whyte fight, he changed his mind and said he would retire after the mandatory defense against Whyte (33)

Fury will still face Ngannou, even if he decides to hang up his boxing gloves.

He stated, "I don’t consider that a true boxing fight."

"That's not an amateur boxing match. It's going to be a special fight. It will take place in a 4oz glove cage at Raiders Stadium in Las Vegas.

"I will be able to complete the crossover fights after I have retired from competitive, champion boxing."
