Anthony Joshua's promoter Eddie Hearn has sent a stern message to Kiwi heavyweight Joseph Parker, as a potential unification fight edges closer to becoming reality.
During the week, Parker's camp released a video saying Joshua has a 'glass jaw' - and that did not please Hearn at all.
In a video message directed at Parker, Hearn called for the Kiwi to step into the ring and test out Joshua's 'glass jaw'.
"There's been a lot of talk, you believe (Anthony) Joshua is the weak link. You believe he has a glass jaw, if that is the case - you better jump on this opportunity. Take this fight, get the win, become the biggest star in world boxing, make your biggest purse by multiple times. Come and join the party in British boxing right now," Hearn said.
Both Hearn and Parker's promoter David Higgins are in talks for a unification bout to take place in March.
Hearn said both camps are edging closer to a deal for Joshua to put his IBO, WBA 'super' and IBF belts at stake against WBO champion Parker, in what would be one of the most significant heavyweight fights in recent years.
"We are single digits, percentages away right now, and we have to be creative," Hearn told Sky Sports UK.
"We have to look the revenue streams. We are already talking about potential venues, potential dates, so it's a good sign.
"I believe they want the fight. They have done a good job on Anthony Joshua, because his message to me last night was very simple: 'Let me at him.'
"He's winding him up, he's pushing the right buttons to get the bite out of Anthony Joshua and Anthony wants to fight Joseph Parker. He wants to do a job on him and we hope it's the next fight for the spring."
