Promotors Eddie Hearn and David Higgins have not exactly seen eye-to-eye throughout the build-up of this weekend's fight between Anthony Joshua and Joseph Parker.

And that certainly didn't change during the start of the press conference on Tuesday afternoon either.

The New Zealander Parker (24 wins, 18 KO's) and Joshua (20 wins, 20 KO's) face each other in an eagerly anticipated world heavyweight title unification clash at the Principality Stadium, Cardiff on Saturday.

But it was the battle between their respective promoters which caught the eye early on as the two world champions went face-to-face.

In a spiky exchange, which you can watch by skipping to 9:00 into the video below, Higgins started off by claiming he wouldn't be taking any bait from either Hearn or Joshua to get riled up and threatened to walk out if either of them tried.

So, of course, what did the Eddie Hearn do? Troll him at the very first opportunity.

Having noticed Parker's promoter nervously shake his leg under the table, the head of Matchroom Boxing said: "If your leg doesn’t stop shaking I’m gonna have to move.

Higgins replied: "Stop talking Eddie, I can smell that silver spoon on your breath."

To which Hearn came back with: “There's only one thing I can smell on your breath and that's last night’s activities.”

Think there would be plenty of fans willing to see Hearn vs Higgins added to the undercard on Saturday...

This a fight already embroiled in pre-match controversy as Higgins said before the press conference that Parker would punish "disrespectful" Anthony Joshua by leaving the final pre-bout meeting if his fellow world champion is late.

Hearn also said prior to the press conference that he wanted Team Parker to repeat their previously strong claims about the 29-year-old to his face. 

The promoter said: “It's great for the fans, what we are seeing is Team Parker, particularly Joseph Parker, growing in confidence as the fight approaches," he told Sky Sports.

He continued: “They're starting to say a few words about Joshua which is brilliant because 'AJ' wants it.

"But as I've said to Higgins before and this goes for Team Parker as well, don't hold your little press conferences in a hotel and do your internet stuff back in New Zealand and say all these things and then when we meet on Tuesday, have your foot in your mouth.”
