Oct 24, 2025 •4 min read•
September 25 in London, United Kingdom at the O2 Arena, a bout will take place between the WBO interim heavyweight champion, 33-year-old British boxer Joseph Parker (36-3, 24 KOs) and the 30-year-old British interim WBA champion Fabio Wardley (19-0-1, 18 KOs).
Joseph Parker. Experience, discipline, desire to seize the opportunity
Joseph Parker is only 33, but his record features a string of names. From Anthony Joshua and Andy Ruiz to Deontay Wilder and Zhang Zhilei. Parker has been a world champion, fought the division's top stars, and now seems likely to be at his peak.
The New Zealander was set to face Oleksandr Usyk. But Usyk injured his back and could not return to the ring in 2025. So Parker decided not to wait and step up against a dangerous opponent.
Fabio Wardley. Power, heavy-handed punching, the ability to surprise everyone
In 2016 Wardley boxed in white-collar tournaments – office worker competitions. At the same time Parker became world champion for the first time. Fabio may not have the same experience, but he has earned the right to fight the best.
In his recent fights the Brit defeated Adeleye, Clarke, Guney in succession. Each time it was a display of power – Wardley possesses a heavy punch and physical readiness to fight with anyone.
The winner of this bout has a chance to take on Oleksandr Usyk. When Wardley had only 4 pro fights, he was invited to Ukraine for sparring with Usyk. Now he is one step away from defeating the toughest opponent of his career and marching toward the undisputed heavyweight title.

Fight prediction for Joseph Parker – Fabio Wardley by Ready To Fight
We estimate the probability of victory, so this cannot be called a full forecast. We consider the most important factors: recent success, the quality of opposition and how they were or were not defeated. Also, the boxers' condition, their potential readiness, and the level of performance in previous bouts.
Parker is an experienced boxer and still young. His recent bouts show that Joseph is entering the peak of his form: physical and mental. Additionally, the New Zealander is extremely fired up. After the official weigh-in he pledged to 'make holes in Wardley'.
Joseph understands that victory now is almost a direct path to Usyk. And thus to the undisputed heavyweight title.
The main strength of Wardley lies in punching power and the ability to find the right moment. Hitting hard isn't enough; you must also land the shot. And Fabio can finish a fight with a knockout even if he's behind, which is a serious danger.
Parker does not possess an iron chin. He has been knocked down more than once, though he often gets up. Therefore there is a risk of him taking a decisive shot. However, strictly boxing-wise, Joseph can handle his opponent. If he doesn't get drawn into exchanges and forgets that in skills he slightly surpasses his opponent.
Estimated probability of victory, considering all factors:
Joseph Parker – 55%
Fabio Wardley – 45%
