Heavyweights Tyson Fury and Dillian Whyte have once again engaged in trading words on social media.
Whyte, who holds the WBC's interim-title, is the mandatory challenger to Fury's belt.
The WBC issued an order which mandates Whyte a world title shot by February of 2021.
Fury is scheduled to face Deontay Wilder in a trilogy fight by the end of the year.
And Whyte is going to fight former WBA world champion Alexander Povetkin on August 22.
Fury, however, has very little interest in facing Whyte in his first outing of 2021. He would much rather fight WBO, IBO, WBA, IBF world champion Anthony Joshua.
Fury's lack of enthusiasm has infuriated Whyte.
Whyte has claimed for months that he battered and dropped Fury during sparring sessions in the past.
"Gypsy coward always conning the public. You forget I've put you down lots before and watched you pathetically sobbing on the canvas you ran away last year when the WBC ordered you to fight me anytime, anywhere, anyhow," wrote Whyte.
But Fury believes Whyte has done nothing to deserve a shot at the world title.
"Dillian Whyte you're a mug, Come back when you achieve something, dosser, A man who [became] famous for getting chinned by AJ," Fury shot back.
Eddie Hearn, who promotes both Whyte and Joshua, beieves there is enough time for Fury to fight both Joshua and Whyte.
"Whyte should take priority over Joshua to get the Fury fight," Hearn told Sky Sports.
"Joshua will fight Pulev in November so won't fight until May, June or July of next year anyway. So there's no reason why Whyte shouldn't get that shot."
