A frustrated Fury took to Instagram on Thursday to say: "Uysk, you proper little s***bag, bog-eyed, gappy-teethed, ugly little rat b*****d
"You little slimy f****r.
"[You] tried all week to get out of it [the fight] begging for the rematch.
"You proper little s***bag, bog-eyed, gappy-teethed, ugly little rat b*****d.
"You tried all week to get to it, begging like a little girl. You got your rematch and you didn't even want to fight at that.
"You little s***house p***y.
"Always know, p***y, that you were never man enough to tangle with the Gypsy King ever in your life, you little s***thouse.
"You little 14-stone coward.
"You little s***bag, you rat little b*****d.
"Your full team know as well and all the lawyers have got [the] full information."
Usyk, 36, will probably now defend his titles against mandatory WBA title challenger Daniel Dubois in a fight Fury was quick to mock.
He added: "You little ugly b*****d, keep running. Fight Dubois at the Copper Box, s**t bag.
"And always know you, or anybody else like ya, could ever tangle with the Gypsy King."
