According to heavyweight contender Dillian Whyte, he received a private message from IBF, IBO, WBO, WBA world champion Anthony Joshua when their negotiations stalled.
The two were in talks for a rematch on April 13 at Wembley Stadium in London, but the negotiations fell apart over money.
Now Joshua is likely heading in the direction of a showdown with unbeaten contender Jarrell Miller on June 1 at Madison Square Garden in New York City.
Whyte however, is going to return on a planned date of April 20 at the O2 Arena.
"He actually messaged me," Whyte told Sky Sports. "It's childish, do you want to make the fight or not? I just thought to myself, you're just an idiot, you clearly don't want to make the fight.
"I just want a fair crack of the whip, that's all. It's nothing to do with who's boss."
Whyte is now pushing to get in the ring with WBC mandatory challenger Dominic Breazeale. Should that scenario not happen, then Whyte would target Alexander Povetkin or Luis Ortiz.
Whyte wants to use Breazeale's status as the WBC's mandatory challenger to secure a direct crack at world champion Deontay Wilder.
He believes the WBC passed him over in favor of Breazeale.
"Probably Breazeale or Povetkin, Ortiz, let's see," said Whyte.
"Hopefully we can fight Breazeale, and I'll get to knock him out, and I'll become WBC mandatory. The decision is meant to be made this week, or as late as early next week."
Whyte is also ranked in the number one spot by the WBO, but he could also be passed over in favor of Oleksandr Usyk - who could become the WBO mandatory challenger to Joshua if the undisputed cruiserweight champion moves up in weight.
"Who? No-one knows what that guy is," said Whyte. "Nothing surprises me in heavyweight boxing, nothing."
