Tyson Fury has sensationally claimed that his long awaited fight against Anthony Joshua is in serious jeopardy. On Thursday, confirmation finally arrived that Fury and Joshua's all-British heavyweight showdown will take place at Cardiff's Principality Stadium on December 11 following months of protracted negotiations to stage the biggest fight in British boxing history.

Saudi boxing powerbroker Turki Alalshikh announced the details had been ironed out for the two foremost heavyweights of their generation to collide but Fury has made the astonishing claim that the fight could be called off.

"Breaking news, Anthony Joshua and Eddie Hearn are trying to pull out the fight," said Fury. "They're saying they're not going to fight now. It's mainly to do with Eddie Hearn's ego. He's making up a million different things and threatening 'we're not gonna fight'"

Sky Sports News have contacted Matchroom Sport for comment. Joshua and Fury, both former heavyweight world champions, have had a long-running rivalry, punctuated by callouts and trash talk but marred by the difficulty of finalising a deal.
