Boxing Schedule July 31–August 1, 2026: Lamont Roach vs William Zepeda Headlines Stacked Weekend with O'Leary vs Chamberlain and More
Boxing fans have a genuinely busy weekend ahead of them, with three separate cards spread across three continents on July 31 and August 1, 2026. The headline attraction is a vacant WBC lightweight world title fight between Lamont Roach and William Zepeda in Las Vegas, but that's far from the only reason to clear your schedule. Dublin hosts a double dose of IBO title action, while Lagos delivers a celebrity boxing rematch alongside a genuine professional bout. Here's a complete breakdown of who's fighting, when, and why each matchup matters.
Main Event: Lamont Roach vs William Zepeda for the Vacant WBC Lightweight
The marquee bout of the weekend takes place Saturday night, August 1, in Las Vegas, Nevada, when Lamont Roach and William Zepeda meet for the vacant WBC lightweight championship. The card is being put on by Golden Boy in partnership with DAZN, with the broadcast set to air on both DAZN and TNT starting at 8:00 pm ET.
Roach arrives at this moment as one of the sport's most respected campaigners, a fighter whose résumé over the past several years has quietly built him into a legitimate world-class operator even before this shot at undisputed-caliber competition. His breakthrough performance came in March 2025 against Gervonta "Tank" Davis, a fight that officially ended in a draw but one that a large portion of ringside media and fans believed Roach had done enough to win outright. Rather than fade after that near-miss, Roach followed it up with another closely contested draw, this time against Isaac Cruz, in a fight many observers again scored in his favor. Two performances that could easily have been recorded as wins on his ledger instead left him with a pair of draws — but they also cemented his reputation as a fighter capable of matching up with anyone in a stacked 135-pound division.
Zepeda, meanwhile, brings a very different style and a very different recent history into the ring. Known as a relentless pressure fighter and one of the hardest workers in the division, Zepeda suffered the first defeat of his professional career about a year ago against Shakur Stevenson. What stood out about that loss wasn't the result so much as the process — Zepeda managed to do something few fighters have accomplished against Stevenson, which is force him into exchanges and turn the fight into a genuine contest rather than a one-sided defensive clinic. That performance, even in defeat, raised his stock among hardcore fans who value action and competitiveness.
Stylistically, this is about as intriguing a matchup as the lightweight division could produce right now: a slick, high-IQ boxer in Roach who has proven he can hang physically and technically with the best in the world, against a come-forward, high-output pressure fighter in Zepeda who has shown he won't be discouraged by adversity. With a major title on the line and genuine stakes attached, this has the makings of one of the better lightweight title fights of the year.
Las Vegas Undercard Highlights
The undercard supporting Roach-Zepeda is stacked in its own right. In the chief support bout, Ray Muratalla defends his IBF lightweight title against Robson Conceicao, adding another meaningful belt to a card that's already built around a vacant world title. Also featured on the card are Raul Curiel and Charles Conwell, who are not fighting each other but are each expected to add firepower to the undercard, along with Gurgen Hovhannisyan rounding out the lineup. With this many live title implications packed onto one card, the Las Vegas show stands out as arguably the most complete boxing event of the summer so far.
Co-Feature Weekend: Pierce O'Leary vs Mark Chamberlain in Dublin
Earlier on Saturday, boxing shifts to Dublin, Ireland, for a Queensberry-promoted card streaming on DAZN starting at 2:00 pm ET. The headline bout sees Pierce O'Leary putting his IBO super lightweight title on the line against Mark Chamberlain.
O'Leary claimed that title in his most recent outing, stopping Maxi Hughes inside five rounds in an impressive performance that announced him as a serious player at 140 pounds. Now he faces Chamberlain, who has posted a modest 1-0-1 record since suffering a loss to Josh Padley back in 2024 — a defeat that, according to reports at the time, cost him significant backing from Saudi boxing power broker Turki Al-Sheikh. Chamberlain's most recent fight was a draw against Jack Rafferty in August 2025, meaning he'll be looking to use this shot at O'Leary's title to reset his career trajectory.
A Second Title Fight on the Dublin Card
What makes the Dublin card particularly notable is that the co-main event is also a title fight. Royston Barney-Smith and Reece Bellotti will meet for the vacant Intercontinental IBO super featherweight title. That belt carries real significance beyond bragging rights — the winner is expected to be positioned for a mandatory shot at the full IBO super featherweight world champion, Jono Carroll. For fans who follow the IBO's title structure closely, this is a chance to watch a fight with genuine championship-lineage implications, not just a supporting-cast scrap.
Between O'Leary-Chamberlain and Barney-Smith-Bellotti, the Dublin card offers two title fights on the same afternoon, giving Irish and UK boxing fans plenty to cheer for well before the Las Vegas main event even gets underway.
Friday Night in Lagos: Portable vs Okocha 2
The weekend of action actually kicks off a day early, on Friday, July 31, with a card broadcasting from Lagos, Nigeria, on DAZN at 1:00 pm ET. The headline attraction here is a rematch between two Nigerian entertainment personalities, Portable (born Habeeb Badmus) and Charles Okocha, who previously met in a celebrity boxing match that Portable won. Both men are well-known figures in Nigerian pop culture, each carrying a colorful public profile that extends well beyond the ring, and Okocha has been vocal about seeking redemption in this rematch.
The chief support bout on the Lagos card pits two other prominent Nigerian entertainment figures against each other — "Mr Real" (Okafor Victor) and "Idowest" (Adekunle Idowu) — both established names in Nigeria's street-hop music scene who reportedly carry a long-running rivalry into the ring.
For fans who prefer their boxing without the celebrity element, the Lagos card does feature at least one legitimate professional matchup: South Africa's Ayabonga Sonjica takes on Nigeria's Taiwo Agbaje in a real contested bout between trained fighters. It's a smaller, more regional showcase compared to the other two cards this weekend, but it adds an entertaining, culturally significant kickoff to the festivities.
How to Watch This Weekend's Boxing Action
For fans trying to plan their weekend around all three cards, here's the quick-reference viewing guide:
Friday, July 31 — Portable vs Okocha 2, streaming on DAZN at 1:00 pm ET from Lagos, Nigeria.
Saturday, August 1 (afternoon) — Pierce O'Leary vs Mark Chamberlain, streaming on DAZN at 2:00 pm ET from Dublin, Ireland.
Saturday, August 1 (evening) — Lamont Roach vs William Zepeda, airing on DAZN and TNT at 8:00 pm ET from Las Vegas, Nevada.
Final Thoughts
