Dillian Whyte insists he wants "to go to war" with Tyson Fury and Anthony Joshua and leave the politics of their fights aside.
The heavyweight title picture finds itself in a confusing state, with Fury being ordered to defend his WBC title against Whyte and Joshua likely to rematch Oleksandr Usyk.
Whyte and Joshua are being encouraged to take step aside deals from those planned bouts to allow an undisputed clash between Fury and Usyk.
Joshua has rubbished claims that he will accept a £15million offer to allow the undisputed fight, with the report also stating Whyte wants £5million.
And Whyte said he is sick and tired of the discussions and just wants to fight.
"I just want war, that's all I want is to go to war with the best, f*** all this he said she said BS," Whyte said whilst tagging Fury, Joshua and Hearn in the Instagram post.
Fury also posted a video message to his heavyweight rivals on Tuesday, stating he is getting sick of "their excuses".
He said: "Tick tick f****** tick tock is the subject of today. Is Dillian Whyte going to fight me, is Anthony Joshua going to step aside?
"Let me know because I am sick of looking at these bums and sick of listening to their excuses. Tick tick tock the time has run out of the bottle and you are all getting a good hiding, you cowards."
Joshua lost his titles when he was outpointed by Usyk last September and immediately activated the rematch clause in an attempt to become a three-time heavyweight champion.
Fury was linked to non-title bouts with Andy Ruiz Jr or Robert Helenius after his fight with Whyte was seemingly off the table.

The purse bids for the world title fight have been pushed back three times and will now take place on Wednesday.
Hearn admitted that Whyte being called as Fury's mandatory challenger has made the title picture more problematic.
"Talks were ongoing for Fury to fight Usyk and AJ to fight the winner but then Dillian Whyte got called as mandatory and had to come into the talks, which made it a lot harder and everyone gave up," he told Boxing Social.
“The plan now is AJ vs Usyk and Fury vs Whyte but those other talks do still rumble on, if I had to bet on the next fights that take place, it would be the two scheduled fights taking place.
“But there is a strong desire to find a way to have an undisputed fight with AJ fighting the winner - and without Dillian I think this would have happened.”
