Joseph Parker

While both fighters are knockout artists, Barry predicts a tough slog for the winner of the May 21 fight in Auckland.

The ramifications are huge with the victor going on to have the mandatory position to fight the winner of this weekend's title fight between champion Charles Martin (US) and Anthony Joshua (GB) in London.

France-based Cameroon fighter Takam tweeted a message to Parker this morning saying he would knock out the South Aucklander at Manukau's Vodafone Events Centre, a provocation that Parker quickly responded to.

The New Zealand heavyweight will take on the France-based Cameroon boxer at Manukau's Vodafone Events Centre on May 21.

NZ Herald reports undefeated Parker, 24, who has fought 18 times as a professional, is said to be in top physical shape already after his short holiday in New Zealand in January which followed his knockout victory over Jason Bergman in Samoa.

The combined purse alone for Parker's clash against France-based Cameroon boxer Carlos Takam will be more than $1 million which will smash the previous record set by the so-called "Fight of the Century" between David Tua and Shane Cameron in 2009 in which both fought for a guaranteed purse of $500,000 each.

A leading rival to rising Kiwi star Joseph Parker in a revitalised heavyweight division, Browne claimed one of the organisation's three world belts with a 10th round stoppage of Uzbekistan's Ruslan Chagaev on March 6.

British fighter Tyson Fury is the WBA unified champion, while heavy-hitting Cuban southpaw Luis Ortiz is the holder of their interim title belt.

Parker takes on Carlos Takam on May 21 in an IBF title eliminator bout and Fury told Parker he should win it easily.

"Good fight for your ranking, but you will smash him," Fury said to Parker in a message.

Parker's handlers have been taunting Browne, who made Australian sporting history by winning a world heavyweight title, beating Ruslan Chagaev in Russia for the WBA's "regular" title (as opposed to the more prestigious unified belt).

Browne, a tattooed, powerhouse slugger from Perth who trains in Sydney, earned a slice of history over the weekend when he stopped Russia's Ruslan Chagaev in 10 rounds to become the first Australian to hold a major heavyweight belt.

With the IBF last week ordering the fight to find a mandatory challenger for the winner of next month's title fight between champion Charles Martin (US) and Anthony Joshua (GB), the promoters have busied themselves with trying to sort through details of where, when and how.

It's an interesting task for Duco Events who look after Parker.

The fight will earn the winner the No 1 mandatory challenger position with the IBF and in line to fight the winner of the looming Charles Martin versus Anthony Joshua title fight.

Takam is a Cameroon-born, French-based fighter with a professional record of 33 wins (25 KOs), two losses (1 KO) and a draw.
