Anthony Joshua will face Joseph Parker in a world heavyweight unification bout on Saturday but he insists no one fight will define his career.

Reigning WBA and IBF champion Joshua will take on WBO title holder Parker in a winner takes all bout at Cardiff’s Principality Stadium with both men looking to move a step closer to unifying the entire division.

Joshua has won all 20 of his professional fights to date by knockout, including last year’s success over Wladimir Klitschko, but he insists no one fight, win lose or draw, will define his career.

“One fight doesn’t define us – if it did, I would be sitting back on the throne after my Klitschko fight,” Joshua told Sky Sports.

“But I’ve got to keep on going. And if you take a hiccup in your career, that shouldn’t define you either.”

Despite playing down the significance of any one fight, Joshua knows exactly how important his heavyweight showdown with Parker could be.

He added: “From my 16th fight when I challenged for the world title, every fight has been a championship fight and something to remember. This fight [against Parker] is very significant – it is history.”

Joshua is priced at 1.11 to beat Parker on Saturday night, while the New Zealander is available at 7.00 and the draw is on offer at 26.00.

Should Joshua secure the victory then a potential showdown with WBC title holder Deontay Wilder could be on the cards for later in the year.
