Anthony Joshua and Tyson Fury have exchanged in a fiery rant about the collapse of their undisputed showdown.
The pair were expected to go to blows in Saudi Arabia, but instead, have gone toe-to-toe on social media.
AJ - the current WBA, WBO and IBF titleholder - branded Fury, heavyweight's WBC king, a 'fraud' after their British blockbuster was left dead by Deontay Wilder's arbitration hearing.
Joshua said: "Tyson Fury the world now sees you for the fraud you are.
"You've let boxing down!
"You lied to the fans and led them on. Used my name for clout not a fight.
"Bring me any championship fighter who can handle their business correctly."
Fury responded instantly and questioned the role of Joshua and promoter Eddie Hearn.
"You're more full of shit than Eddie, spouting absolute shite!
"Your full team knew there was an Arbitration going on, it was out of my hands!
"But i tell you what if i'm a fraud let's fight this weekend bare knuckles till 1 man quits? let's put up 20 mill each."
AJ then replied with a knockout.
"If there was an arbitration going on, why announce to the world we are fighting! The fight was signed! UNDISPUTED.
"Bare knuckle? You're a good kid, don't play with me Luke!
"I'll slap your bald head & you'll do nothing! Waste man."
"Not going in to the details on line!" Fury said.
"You'll slap me about will you dosser please come and try bum, I'm waiting... Femi AKA Bottlejob! 24/7 365.
"Ready. I'll smoke wilder first then you will get yours aswell."
Joshua is now set to take on WBO mandatory challenger Oleksandr Usyk with late August expected to be the date.
The organisation has given Joshua 48 hours to try and secure a fight with Fury before demanding he fights Usyk next.
Fury, meanwhile, could face Wilder as soon as July 24 after Bob Arum revealed he had reserved the Allegiance Stadium for the bout.
"We're not paying Wilder to step aside," Arum told ESPN.
"It's better to get rid of him and go about our business. We can make the Fury-Joshua fight for November or December."
Forget the fighters, it's the British fans that have been let down.
Not only did they accept the summer showdown would take place in the Middle East, they were also prepared to pay up to £30 for the pay-per-view during a pandemic.
A two-fight deal had been agreed followed by a site fee before Fury released a video to confirm an agreement had been struck this week.
Less than 24 hours later, Fury was ordered face Wilder for a third time by September 15.
A coincidence? Very unlikely.
Both fighters have missed out on history as well as a big pay day but more importantly, it has lost a generation of boxing fans.
Lennox Lewis was crowned the last undisputed champion in 1999 and by the looks of it, we will be waiting a long time until we see another one.
