Schoolteacher Stops A Two-Weight World Champ — Zak Chelli Pulls The Upset Of 2026

• Supply teacher Zak Chelli (now 17-3-1, 9 KOs) stops David Morrell (12-2) in the 10th and final round of a 10-round catchweight fight at 187 lb on the Wardley-Dubois undercard at Co-op Live, Manchester
• Morrell, The Ring's #5 light-heavyweight and an unbeaten WBA super-middleweight and interim light-heavyweight title-holder coming in, took his first stoppage loss as a professional. Chelli was a 1/12 (-1700) underdog
• The win shoots Chelli straight to the front of the WBO light-heavyweight queue — the bout was set up as the eliminator slot after Callum Smith withdrew injured. Chelli took the fight on four weeks' notice and hadn't boxed for ten months

The Moment

Right then. Let's not beat around the bush — what we have just watched is a supply teacher from Fulham stop one of the most avoided 168-pounders on the planet, in the last round of a fight he was supposed to lose every which way. Morrell was 1/12. Chelli was 15/2. The bookies had this fight finishing inside seven for the Cuban-American. Instead it went the other way. After nine increasingly stubborn rounds — Chelli boxing on the front foot, refusing to be backed up, eating Morrell's left hand and answering with shorter, sharper work to the body — the round-10 bell rang on a fight that was, somehow, still alive. And then the schoolteacher did the unthinkable. He kept his head, then he took it.

Chelli's Story Is Boxing At Its Very Best

Make no mistake, this is the sort of night that reminds you why you bother with this sport. Zak Chelli is 28, a dad of one, a business management graduate from the University of Surrey, and full-time he is a supply teacher. He can teach maths, he can teach science, he can teach physics — he covers anything below GCSE level and sometimes goes up to A-level when the school is short. He also runs boxing sessions in West London schools two or three times a week — mostly with kids who have special educational needs or behavioural issues, kids who don't always sit easy in a classroom. He told The Ring on the morning of the fight that the kids in those schools just keep asking him: "sir, sir, when's your next fight?" He had to keep telling them he didn't know. That is a man who, ten months ago, was waiting around with no fight on the cards. He lost his British and Commonwealth super-middleweight titles to Callum Simpson in August 2024. He had one bounce-back win in June 2025 and then nothing. When Callum Smith got injured and pulled out of the original April 18 eliminator with Morrell, Chelli got a phone call. He had four weeks. He took it on the spot. He told The Ring he'd been keeping fit precisely in case of this exact eventuality. Destiny, he called it. Turns out he wasn't wrong.

What Morrell Brought Into The Ring

And let's not undersell what Morrell came in as. David Morrell — Cuban-American, southpaw, world-class — had held the WBA super-middleweight regular title and the WBA interim light-heavyweight strap. He came in 12-1, his only blemish a competitive decision loss to David Benavidez. He was The Ring's number five at light-heavy. The 12 wins included nine knockouts. He had spent the build-up openly calling for a Benavidez rematch and naming Callum Smith as his preferred next opponent. He saw Chelli as a one-night inconvenience on the way to bigger nights. Morrell will not have a single excuse he can lean on. He had a full camp. The fight was at his preferred catchweight of 187, just under light-heavy. He was the favourite by every conceivable metric. He just got beaten.

What Chelli Wins From Tonight

A lot. The bout was carved out of the WBO light-heavyweight eliminator slot — the one that had been ticketed for Morrell vs Smith before Smith pulled up — which means Chelli now slides directly into the front of that queue. He becomes the man the WBO mandatory has to come through. Suddenly a fighter who couldn't get a date six months ago is one fight away from a world title shot. The bigger picture matters too. Chelli has, in one night, gone from "former British super-middleweight champion who was treading water" to one of the names of the year in British boxing. The Ben Whittakers, the Joshua Buatsis, every domestic light-heavy or super-middle on the rise — they all have to look at Chelli now and ask whether they want it. The leverage swing in his career is enormous.

Where This Leaves Morrell

A first stoppage loss on his record at age 28, and on his UK debut, no less. Morrell is still a top-tier 175-pounder on talent — make no mistake, he can rebuild and he probably will. But the aura is gone. The Benavidez rematch he was lobbying for becomes much harder to sell. The Callum Smith fight he wanted next becomes a different fight. Eddie Hearn and his team will need a thoughtful comeback plan rather than a rush back to the top of the food chain.

UK Boxing's Depth Speaks Again

If you know, you know — British boxing is having one of its proper eras. Fabio Wardley headlines a heavyweight title fight tonight. Daniel Dubois is in the other corner. The WBO heavyweight, super-middleweight, and now possibly the WBO light-heavyweight pictures all run through Britain. Add Chelli's name to that depth chart now. Add him in capitals. And add the framing. A supply teacher. Four weeks' notice. Ten rounds with The Ring's number five. Final-round stoppage. The next time one of his Year 9s asks him "sir, sir, when's your next fight?" — the answer might just be a world title shot.

My Verdict

This is the upset of 2026 in British boxing. Possibly globally. Bring me a bigger one and I'll listen. Chelli does not get the credit he deserves tomorrow morning because Wardley-Dubois will rightly own the back pages, but make no mistake — what happened on the undercard is a story that runs and runs. Boxing is brilliant when it gives you nights like this. It happens twice a decade, maybe. And it's happened tonight in Manchester to a teacher from Fulham. Levels, mate. Absolute levels.
