Eddie Hearn, promoter for IBF, IBO WBA heavyweight champion Anthony Joshua, was left stunned after watching the press conference held by promoter David Higgins and his star fighter, WBO heavyweight champion Joseph Parker.
Parker and Higgins held a press conference with the media in Auckland, where they dared Joshua to accept what they called their "final bottom-line" of a 65-35 split in the British boxer's favor.
They showed the media in attendance a video - put together by Duco - where numerous fighters claimed to have dropped Joshua in sparring and the amateurs, and they also showed footage of Joshua getting shook up in several of his recent pro fights.
Team Parker said it was strong evidence to back their position that Joshua has a "glass chin."
"It's the worst-kept secret in British boxing," said Higgins. "It's a genuine weakness, backed by fact. There is no disrespect here - it's all in the public domain and it's all factual.
"We want to build the hype in the UK. We will cop some hate, as we often do ... but this is all fact. And it's fact that Joseph has a granite chin ... he's never been dropped as an amateur, in sparring or as a professional."
According to Higgins, they are officially dropping their demand to 65-35 and won't go any lower. They have left the ball in the court of Joshua and Hearn.
"We want to make the fight happen, we are not all hype," Higgins said. "It's now up to Eddie and Anthony. There are no excuses ... they can have 65 percent of a very, very big pie. Our message to Anthony Joshua - and it's a serious message - is we want the opportunity to test your chin so much that we'll let you keep 65 percent of the profit, even though it's an intercontinental unification. Show Parker some respect and make the fight."
Hearn, who hopes the two sides can reach an agreement, felt the presser did very little to boost the value of Parker or the boxer's marketability for a Joshua unification.
"You've got to love this David Higgins - he is absolutely off his swede," Hearn exclusively told Sky Sports.
"We are getting closer on a deal, but holding a press conference in a broom cupboard with a promotional video that looks like it's been done by my eight-year-old daughter is not the one, in terms of justifying your commercial value. Negotiations are ongoing and we are hoping a deal can be reached."
