A pair of two-division world champions will take their talents down under as Jermall Charlo and Stephen Fulton Jr. return to the ring in separate undercard attractions taking place Saturday, July 25 (U.S. date) from Afterpay Arena in Sydney, Australia on the Errol Spence Jr-Tim Tszyu undercard(PRIME VIDEO PPV).
The undefeated Jermall Charlo will step in to face Australia’s Koen Mazoudier in a 10-round super middleweight battle, while former 122 and 126-pound world champion Stephen Fulton Jr. will face Australian former title challenger Liam Wilson in a 10-round super featherweight attraction.
The pay-per-view will kick off with undefeated rising Australian Olympian Callum Peters entering the ring for 10 rounds of middleweight action.
“It’s an honor to headline the greatest fight card ever assembled in Australia,” said Tszyu. “It’s an enormous privilege for me because I know how rare this is for fight fans to have a card of this magnitude on home soil. Every time I step into that ring, I’m not just fighting for myself — I’m fighting for Australia and for everyone who’s ever believed in me. Errol Spence Jr. is a legend of this sport, one of the greatest to ever do it, but on July 26 I get to take him out once and for all. Moments like this are history making. They are rare, you don’t want to miss it.”
**JERMALL CHARLO VS. KOEN MAZOUDIER**
A former world champion at 154 and 160 pounds, Jermall Charlo will make his second consecutive appearance against super middleweight competition as he looks to move closer to a world title opportunity against the upset-minded Koen Mazoudier, who enters this 10-round matchup on a three-bout winning streak.
Charlo’s (34-0, 23 KOs) quest to become a three-division world champion in the stacked 168-pound division began in May 2025, as he returned from a lengthy layoff to stop veteran Thomas LaManna in six rounds. A native of Houston, Texas, Charlo first joined the ranks of world champion in 2015 with a dominant knockout of Cornelius Bundrage, and would go on to defend the title three times, including an emphatic stoppage of the then-undefeated Julian Williams in December 2016. Trained throughout his career by the renowned Ronnie Shields, Charlo would then begin a middleweight run that saw him earn the WBC championship and add victories over top contenders including Sergiy Derevyanchenko, Matt Korobov, Hugo Centeno Jr. and more.
“It feels great to be back in the ring and to take my talents Down Under to Australia,” said Charlo. “Koen Mazoudier is going to be looking to make a name off me, but he underestimates how hungry I am. These guys ain’t seen nothing like this. It’s the USA vs. Australia and Jermall Charlo is coming to take over. Lock in with me on July 25 and watch me put on a show.”
A native of Blacktown, New South Wales, Australian, Mazoudier (15-4-1, 6 KOs) turned pro in 2018 after an accomplished amateur career, reeling off six consecutive victories. Of the blemishes on 30-year-old’s record, two came by narrow majority decisions, with one of his other losses eventually being avenged as he defeated Wade Ryan by unanimous decision in 2022. His other loss came at the hands of undefeated Australian star Nikita Tszyu, younger brother of Tim Tszyu. The 2024 showdown against Tszyu was within two points on two judges’ cards when the bout ended in round nine. Mazoudier has bounced back effectively, winning three-straight fights in 2025.
“I know I’m the underdog,” said Mazoudier. “Everyone knows I’m the underdog. I don’t care. I’m coming to spoil the party and dethrone a legend. I’ve never taken a backward step in my life, and I’m sure as hell not starting on 26 July. I’m going to bring everything I’ve got to get the result. I’m the real life Rocky.”
**STEPHEN FULTON JR. VS. LIAM WILSON**
Having faced the best in the sport while earning pound-for-pound consideration, Stephen Fulton Jr. will look to get back in the win column on enemy soil as he takes on rugged and experienced Australian contender Liam Wilson in a pivotal 12-round showdown for each fighter.
Born and raised in West Philadelphia, Pa., Fulton (23-2, 8 KOs) hopes to bounce back from a defeat to elite 130-pound world champion O’Shaquie Foster in December. His previous outing saw him become a two-division champion by vanquishing his longtime rival Brandon Figueroa in their February rematch via decision to capture the WBC Featherweight World Championship. It was Fulton’s second fight since a July 2023 challenge that saw him travel to Japan to take on undefeated Japanese superstar Naoya Inoue, eventually dropping the road contest in round eight. In his previous 14 professional fights before facing Inoue, the 31-year-old had established himself on pound-for-pound lists by beating eight previously undefeated fighters. Fulton first became a world champion by taking the super bantamweight title from Angelo Leo in January 2021, before unifying against Figueroa in their first fight.
“I expect Liam to be on his A-game and take this fight as an opportunity to get a shot at the title,” said Fulton. “This fight is to show that I am nowhere near finished and to redeem myself after my last performance. I let my fans and peers down in my last fight, as well as myself, so this is me coming back out strong!”
Currently riding a five-fight win streak, Wilson (18-3, 10 KOs) most recently knocked out Rodex Piala to kick off his 2026 campaign in January. The 30-year-old gained a wealth of experience against elite competition in giving spirited challenges to former world champion Oscar Valdez in 2024 and multiple-division world champion Emanuel Navarrete, who he dropped in round four of their 2023 world title clash. Representing his native Redcliffe, Queensland, Australian, his only other defeat was quickly avenged when he stopped Joe Noynay in two rounds in March 2022. While his previous championship-level fights came in the U.S., Wilson will look to benefit from the home turf advantage against Fulton on July 25.
“Fulton has been a champion in two divisions,” said Wilson. “I respect that. But I’m ‘Mr. Damage’ — I don’t do easy nights and I don’t do backward steps. On July 26, he’s going to find that out.”
**CALLUM PETERS VS. TBD**
The highly-touted middleweight prospect Callum Peters will put his undefeated record on the line again in a 10-round attraction that follows up his first fight to go the 10-round distance in May.
After representing Australia at the 2024 Olympics, Peters (7-0, 6 KOs) turned pro in December 2024 and put together six consecutive knockouts, with only one opponent making it past round two. The 23-year-old most recently dominated his toughest opponent to date in Joeshon James, beating the then 10-1-2 contender by wide margins on all three cards. A native of Adelaide, South Australia, Peters also owns an April knockout over Delio Mouzinho that streamed live on Prime Video.
