Jan 20, 2026 - 10:30

Callum Walsh and Carlos Ocampo are headlining the first of Dana White’s Zuffa Boxing events.

Walsh is putting his unbeaten record on the line as he takes on the 41-fight Mexican at the top of Zuffa Boxing’s Z01 card.

The last time Walsh was in action, he claimed a unanimous decision win over Fernando Vargas Jr on the undercard of Canelo Alvarez vs Terence Crawford.

Ocampo is an experienced campaigner and has only been beaten by Errol Spence Jr, Sebastian Fundora and Tim Tszyu in his 41 outings so far.

The Mexican is coming off three consecutive stoppage wins against limited opposition in his home country, but is hoping to deliver a hammer blow to Dana White’s longest-held boxing prospect.

Walsh will be looking for a statement on the inaugural bill, White that he is backing the right man for world domination in the sport.

Zuffa Boxing’s debut card has been scheduled as a precursor for the first UFC event of 2026, Paddy Pimblett vs Justin Gaethje, which takes place a day later.

“We have this kid named Ocampo, who is a seasoned veteran. His only losses are in title fights – three title fight losses.

“He has more knockouts than Callum has fights. Callum, undefeated, 15-0, and it’s the main event.

“Should be a badass boxing event.”

Alongside the official announcement for the event, White said: “The first Zuffa Boxing event is filled with the best up-and-coming talent, hungry and excited to prove that they will be future world champions.

“The top three fights feature four fighters who are undefeated, including 15-0 Callum Walsh as he takes on the 38-3 Carlos Ocampo, who has more knockout victories than Callum has total professional fights and his last three wins have come by knockout.

“I’m looking forward to bringing great fighters and incredible fights back to fight fans.”
