WBO heavyweight champion Joseph Parker has poured gasoline in the fire, as he continues to bait IBF, IBO WBA champion Anthony Joshua to accept an agreement for an unification in early 2018.
Parker and his promoter, David Higgins of Duco Events, 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.
"AJ and I want to unify, and they [the promoters] should make it happen," Parker said. "I'm happy my team is taking care of that. I'm staying in shape, in case it happens."
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."
The two sides started at 50-50 terms, then Team Parker said they would take 60-40, and now they are dropping to 65-35 and won't go any lower. They have left the ball in the court of Joshua and his promoter, Eddie Hearn of Matchroom.
"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. We want an open book on revenue share. We have gone from 50 to 40 to 35 percent of the net profit and are willing to take the fight next. We feel anything less is disrespectful or a disgrace. Given Joshua has two belts and Joe has one, a share of about two-thirds and one-third split seems natural justice."
If Joshua and Hearn are not willing to do a 65-35 deal, then Parker and Higgins have a backup plan already in place - with former champion Lucas Browne waiting in the wings.
