Deontay Wilder believes Eddie Hearn is holding up a possible unification clash with Anthony Joshua as the American continues preparations to face Luis Ortiz.
Since Joshua defeated Carlos Takam last October, Wilder has made it clear he wanted to battle 'AJ' next, although Hearn's main aim was to make sure his fighter unified all other titles available first.
The Briton will have the opportunity against Joseph Parker on March 31, but that still isn't where Wilder is expected to come into play.
Joshua is set to take on Alexander Povetkin after the Russian was added to his bill at the Principality Stadium as the WBO and WBA's stipulated mandatory challenger.
Fighting Povetkin should hold the IBF (who will want the Kubrat Pulev situation sorted) down for one more fight at the end of the year - which fingers crossed - could be Wilder in Las Vegas should everything go to plan.
For now, though, Wilder has accused Matchroom Boxing and Sky Sports of stalling.
"Everybody wants to see the fight," said Wilder to ESPN.
"The only people that don't are his promoters. They already know how big of a risk this really is.
"They should be worried but how long do they really think the public, the fans of boxing are going to allow them to stay away from me? This is the biggest fight in our era."
On his own credentials, as he bids to hit 40-0 against Ortiz next month, Wilder added: "I am the most exciting, most entertaining fighter in the heavyweight division.
"Nobody in the heavyweight division is doing what I am doing. Nobody in history is doing what I am doing.
"If they feel that they want to unify, then, hey, you must go through me. All roads lead to Deontay Wilder because I am going nowhere, no time soon," he said.
