Heavyweight contender Tyson Fury has exploded after being advised that promoter Eddie Hearn was doubting Fury's ability to make good on a promise to score a knockout in the upcoming rematch with WBC world champion Deontay Wilder.

Fury will challenge Deontay Wilder for a second time on February 22 at the MGM Grand in Las Vegas.

They fought to a controversial twelve round split draw in December of 2018 in Los Angeles.

Fury has promised to end the fight by knockout. In fact, he vowed to end Wilder's reign within two rounds of action.

Hearn could see Fury winning - but not by knockout, as he doesn't view the 'Gypsey King' as a big puncher.

In response, Fury took full aim at Hearn and his star fighter, IBF/IBO/WBA/WBO heavyweight champion Anthony Joshua.

"You know what? I don't really care what Eddie Hearn says because Eddie Hearn is a p-ssy. And I don't even know if I can say that live on radio but Eddie Hearn is a p-ssy and and so is AJ (Anthony Joshua). And if they have any nuts about them they'd have fought me years ago. We're from the same country you know and he's been avoiding me for a long long time," Fury told The Main Event on SB Nation Radio.

"[Joshua] wasn't man enough to step up and fight Deontay Wilder so he took an old fat bald-headed fella to come out of retirement to stand up for his country. To stand up for his nation because they were getting made to look like clowns. So what Eddie Hearn and Anthony Joshua says you can't really take too much from that. You know, they speak a lot of hot air and don't back it up.

"I recently saw [Joshua] get knocked out by an old fat fella so don't come and talk to lineal champion about performing because you know he's a hit and miss performer completely."
