Joseph Parker vs. Fabio Wardley Confirmed for Oct 25 ‘All or Nothing’ at The O2.

London, England, UK - It’s on. A classic heavyweight showdown will headline London’s O2 Arena when Joseph Parker takes on Fabio Wardley in All or Nothing on Saturday, October 25, live worldwide on DAZN PPV.

The event, promoted by Queensberry Promotions in association with Platform Sport, brings together two of the division’s most in-form big men for a fight that could reshape the heavyweight pecking order.

Parker’s resurgence

New Zealander Parker (36-3, 24 KOs) enters on the back of a blistering run. In the past year, he’s beaten Deontay Wilder, dethroned Zhilei Zhang for the WBO interim title, and destroyed Martin Bakole in two rounds in his first defence.

Once the full WBO champion, Parker has rebuilt since losses to Anthony Joshua (2018), Dillian Whyte (2018), and Joe Joyce (2022). Now 33, his form under trainer Andy Lee has rekindled calls for another world title run.

Wardley’s fearless rise

Unbeaten Fabio Wardley (19-0-1, 18 KOs) brings raw power and growing experience. He became British champion in 2022 with a win over Nathan Gorman, defended against David Adeleye in Riyadh, and split two crowd-pleasers with Frazer Clarke — a draw in March, followed by a brutal first-round KO in the rematch.

In June, Wardley stopped Justis Huni at Portman Road in a statement win that confirmed his arrival on the world stage.

Promoter quotes

“This will be a corker of a heavyweight clash and one which will shine a huge light on the division,” said Frank Warren. “Neither Joe or Fabio wanted to wait about and protect their positions… I believe this is a genuine even-money fight with a mesh of styles that will be eye-catching and highly crowd-pleasing.”

“We promised to keep firing up this heavyweight division,” Warren added. “It is wonderful to be back at The O2 Arena with All or Nothing. This event will be the hottest ticket in town.”

Michael Ridout, DAZN EVP, , said: “Joe is coming off 3 brilliant wins and is looking to cement his position at the top of the rankings whilst Fabio continues to prove all his doubters wrong. All the drama will unfold on another special night live and exclusive, worldwide on DAZN.”

Why it matters

In a heavyweight landscape where much of the top 30 remains inactive or “TBA,” Parker–Wardley is action in real time. The winner cements elite status and edges closer to a mandatory shot at the ultimate prize.
