Jai Opetaia jumps a division to fight Deontay Wilder on the night Fury and Joshua finally meet

For years Tyson Fury against Anthony Joshua was boxing’s great unmade fight. It is now booked: the two former world heavyweight champions meet at the Principality Stadium in Cardiff on Friday, December 11, streamed live on Netflix to subscribers at no extra cost.

But for Australian fans the fight to circle sits further down the poster. Jai Opetaia, the unbeaten cruiserweight champion, is moving up to heavyweight to face Deontay Wilder.

Why is Opetaia taking this risk?

Opetaia has run out of cruiserweight questions. He is 31-0, has held the IBF title since 2022 and is widely rated one of the best fighters in the world at any weight. He went to the London 2012 Olympics at just 16.

Heavyweight is where the money and the attention are, and Wilder offers the fastest route to both. Opetaia has called it the biggest test of his career.

How dangerous is Wilder?

Very. The man from Tuscaloosa, Alabama held the WBC heavyweight title from 2015 to 2020 and built a 45-4-1 record on a right hand that ended most of his fights early. He fought Fury three times between 2018 and 2021, and most recently beat Derek Chisora on a split decision in April.

Wilder has lost more often in recent years than in his prime. For Opetaia, the question is whether a cruiserweight’s speed and timing can keep him clear of a heavyweight’s power for long enough to find his own openings.

What is at stake in the main event?

Both of Fury’s two defeats came against Oleksandr Usyk in 2024. Joshua’s four losses include stoppages that once seemed unthinkable. The winner walks out of Cardiff as the biggest name in British heavyweight boxing, with a strong claim to a world title fight; the loser, at this stage of both careers, may not get another night like it.

Who else is on the card?

Netflix has confirmed two more heavyweight bouts. Martin Bakole, who last fought in May 2025 in a majority draw with Efe Ajagba, faces Solomon Adebayo. Da’Mazion Vanhouter, who stopped Ivan Balaz in the first round in London only days ago, meets Michael Essomba.

When can Australians watch?

The card runs on Friday night in Cardiff, which is Saturday morning, December 12, in Australia. The main event is expected around 1am UK time, which would be about 9am AWST and noon AEDT. Ring-walk times are usually confirmed in fight week.
