Heavyweight boxing moved closer to having an undisputed world champion after it was announced Sunday that Britain's Anthony Joshua and New Zealand's Joseph Parker will meet for a multiple title bout in Cardiff on Mar. 31.
Joshua will put his WBA, IBO, IBF belts on the line against Parker, the World Boxing Organisation champion.
Matchroom Boxing, Joshua's promoters, said the bout would take place at the Principality Stadium, best known for staging Wales rugby union internationals.
Joshua, the London 2012 Olympic super-heavyweight champion, unified the WBA, IBO and IBF titles with a dramatic and hard-fought win over Wladimir Klitschko at Wembley in April before retaining both belts against Carlos Takam in a late-stoppage win in Cardiff in October.
Parker, 26, became the WBO champion in December 2016.
He made his British debut last year with a majority points win over challenger Hughie Fury, a cousin of former world heavyweight champion Tyson Fury.
Parker's performance against Fury did not impress some ringside observers.
But Parker was adamant his punching power would test Joshua.
"The only thing my mind is focusing on now is that the fight is happening, but sh*t there is a lot of work to do," Parker said to Cillian O Conchuir.
"The weight isn't an obstacle. My body is growing and we're looking to get a bit more muscle. But the lighter I am, the better I will be. I am more agile, I move a lot better when I am lighter. I think the goal for us is to be under 110 kgs, maybe around 108 kgs or 109 kgs. I have 10 weeks to really focus, to really give it everything. This is make or break.
"But you can never predict what is going to happen. It comes down to the day, who performs better and who feels better. This will be the biggest fight of my life so far and the excitement that I have to be part of this massive event fighting someone like Joshua who is undefeated. The challenge he is going to bring, I am over the moon. I am excited. The world should have one champion."
