Joseph Parker steps up training outside as heavyweight champ prepares for Anthony Joshua showdown

JOSEPH PARKER is into the final stages of his training as he prepares to fight Anthony Joshua at Cardiff’s Principality Stadium on March 31.

The Kiwi boxer is the big underdog to snare the IBF, IBO and WBO heavyweight world titles, to add to the WBA strap he has already got.

But Parker is ensuring no stone is left unturned in his quest to become the unified champ.

The 26-year-old uploaded some photos of his recent outdoor training ahead of the blockbuster showdown in Wales.

And Parker will be hoping AJ has taken his eye off the ball as talk of a fight against Deontay Wilder continues.

The two heavyweight world champions remain on a collision course after Wilder knocked out dangerous Cuban Luis Ortiz in Brooklyn on Saturday.

But if Parker upsets the odds and beats AJ, it will be him set for an ‘all the belts’ scrap against the Bronze Bomber.

Speaking after his  latest KO win, Wilder said: “I always said I want to unify all the titles. My goal is to unify.

“I am the most dangerous in the world, the baddest man on the planet. I proved that tonight.

“Soon there will be one champion, one face, one name – that will be Deontay Wilder.

“It’s not about how big your muscles are – it’s about the heart.”
