As reported on Wednesday on BoxingScene.com, Joseph Parker's promoter says a fight between the New Zealander and Anthony Joshua "has never been closer" after a purse split was formally agreed.
Joshua, the star of the heavyweight division who holds the IBF, IBO and WBA belts, is expected to take on Parker - the WBO champion - in March or April next year.
Last week, Joshua's promoter Eddie Hearn said he was "close to a deal with Parker" that would see the two unbeaten fighters meet.
David Higgins of Duco Events, who promote Parker, told Stuff, that he's confident in his boxer's ability to expose what their side is claiming to be a glass jaw.
"I spoke to Eddie Hearn and he is sunning himself in the Carribean drinking cocktails. He didn't clarify whether it was on his own private island or not," Higgins said.
"But Eddie needs to have a good rest because it's the calm before the storm. We think he has made a grave mistake by feeding AJ to Joseph Parker ... he is sending his glass goose to the slaughter.
"Why is Anthony Joshua a glass goose? Because he says stupid things about Robert Mugabe and suchlike in the media, that makes him a goose. The reason he is glass is he is getting flattened all the time in training camps. His chin is a myth."
The contest is going to land in a stadium in the UK, with dates in March and April being pursued by the two teams.
"This is another case of New Zealand taking it to the world," Higgins said.
"We are the underdog, we are going into his backyard in front of a cauldron of British fans. But we are confident that we can go to England, beat Anthony Joshua and go a step closer to unifying the division by bringing those two other belts back to New Zealand.
"Joseph takes pride in fighting for New Zealand and Samoa and we are excited about this opportunity."
