Joseph Parker

Parker will put his WBO strap on the line at the Principality Stadium, while Joshua's IBF and WBA belts will also be draped around the victor on March 31.

The pair will finally come together after months of negotiations between the representatives of both camps, the bout confirmed early in 2018.

Ahead of the fight Joshua said he hoped Parker would be fit enough to go the distance in their 12-round contest, and Parker has provided an update that should please the British boxer.

"Training has gone really good," he told Sky Sports News at his Las Vegas training camp.

The highly-anticipated bout will see Joshua and Parker put their IBF, WBA Super, IBO and WBO belts and unbeaten records on the line, as both fighters aim to become the first undisputed heavyweight champion since Lennox Lewis in 1999.

Many pundits out of the UK believe Joshua's size and skill will prove too much for Parker at the Principality Stadium on April 1 (NZ time), but Wilder has a different perspective.

Speaking to Andrew Gourdie and Jim Kayes on RadioLIVE's Sunday Sport, Wilder issued a warning not to be deceived by the Briton's chiselled physique.

The 26-year-old is not convinced the 6ft9 Briton offers much insight into the type of bout they can expect in Cardiff.

Speaking to Andrew Gourdie and Jim Kayes on RadioLIVE, Parker admits he appreciates the support, but is happy with the sparring partners they have assembled.

"Tyson Fury's a great guy, but with all due respect to him, I don't think it's the right person to spar because he moves around well for a big guy and he doesn't come forward, and he's a lot taller.

 “Over a span of two years and through Joe’s journey before he became a WBO Champion to his two title defense fights against Cojanu and Fury, we were able to give the opportunity to some lucky customers to watch Joe fight in person. Now as he prepares for what is believed to be his biggest and most important fight yet, we are once again giving the chance for our customers to join Parker and support his team in Cardiff, Wales and be our representatives for all of us here in Samoa who will be watching on TV” said CEO Farid Mohammed.

The world champ spoke to Mantis on Niu FM Breakfast live yesterday from London, after appearing at his first pre-fight conference with Joshua in London.

Parker stood face to face with his opponent for the first time since the announcement of the fight.

He says he's happy the talk is done because he hasn't been feeling like his genuine self.

“Now that the fights locked in, it’s back to the person that I am, so some of the things that I said and the way that I acted, it wasn’t really me and I felt uncomfortable doing it,” he says.

WBA, IBF and IBO heavyweight champion Joshua and WBO belt-holder Parker are set for a unification bout at Cardiff's Principality Stadium on March 31 in a hotly anticipated clash.

In November, before the fight had been agreed, the Parker camp released a video which showed Joshua being knocked down during his amateur days, as well as clips from former sparring partners claiming they had floored him.

At a media conference on Tuesday, Parker's promoter David Higgins spoke up about the issue.

At least, that's what Sala Parker keeps telling herself.

The 26-year-old South Aucklander's title unification fight against Anthony Joshua was finally made official late Sunday night, with an April 1st (NZT) date booked for Cardiff's Principality stadium.

It shapes to be the biggest stage arguably any New Zealand sportsman has ever appeared upon, with an audience of over 80,000 inside the stadium and the eyes of the wider sporting world certain to be tuned in.

The Briton's promoters have confirmed he will put his IBF and WBA belts on the line against WBO champion Parker at Cardiff's Principality Stadium, ending months of lengthy and protracted negotiations between both camps.

Both men will put undefeated records on the line, while the victor will move a step closer to unifying the heavyweight division for the first time since Lennox Lewis achieved the feat in 1999.

WBO champion Parker is desperate to fight WBA and IBF champion Joshua and the big Brit believes a March or April bout in the UK is "realistic".

It seems Parker's unorthodox methods of prompting Joshua into taking the fight are hitting a nerve.

Team Parker have released videos to question Joshua's "glass chin" and repeatedly accused him of greed as the Kiwis haggle for a 35 per cent cut of the net profit from what would be a mega-fight.

Joshua has tried to steer clear of the trash talk though he admits there is a place for the "gutter" element of boxing.

Klitschko, who retired after being knocked out by Joshua in their April fight at Wembley, says he is comfortable with his decision to step away from the boxing ring and believes Joshua is the fighter to carry the glamour division forward.

"I have passed the torch to the younger lion," Klitschko told The Sun.

"I wish, from the bottom of my heart, he continues to carry this torch for a long time and is very successful just like I was. Joshua is capable of unifying the division, absolutely."
