Before MMA: weightlifting, refereeing and a first failure
Arras, April 1995. Before the cage, there was weightlifting. Matthieu Letho Duclos rose up to the French weightlifting championships before switching to fighting. The build was already there, the career not yet.
His first pro steps date back to 2019. The fight ended by submission, a heel hook, and an immediate lesson. This is not the story of a prodigy, it’s the story of a guy who takes hits before learning to give them back.
Did you know?
Before being a name on an UFC card, Duclos was a familiar face in French MMA online: he worked as a referee, notably on YFC formats broadcast by IbraTV. The public already knew him. But on the wrong side of the cage.
From Bellator to Contender Series: two doors slammed shut
May 2022, Bellator 280, Accor Arena. Same venue, different story: Youcef Ouabbas stops him by TKO in the first round. Duclos later said he thought his career was over that night.
August 2024, second door. On the Dana White's Contender Series, the format that hands out UFC contracts, Brazilian Marco Tulio stops him in the second round. The contract goes elsewhere. At 29, with two failures on the two biggest accessible stages, the window was starting to close for good.
How do you come back from a failed dream?
By going home. The Northerner did what few “almosts” accept to do: rebuild on the lower level, without American cameras. Hexagone MMA middleweight champion since February 2024, he has defended his belt three times.
The counter shows five consecutive wins after the Contender Series, mostly before the limit. The last one, in April 2026 against Ilian Bouafia, ended due to the opponent’s injury. No showcase, no spotlight. Just a fighter putting the pieces back together at home for two years.
The camp that got him back on his feet
Duclos trains at Woirin Team Elite, the structure that trained Benoît Saint-Denis before his camp change. Orthodox stance, 1.91 m with a reach of about 1.95 m, raw power rather than volume of strikes. A committed power puncher, in a division that doesn’t forgive approximations.
The exact moment: the left counter that ends the fight (RMC Sport Combat).
The left counter: 4:35 to settle the score
Bercy, September 5, 2026. First round, and the scenario goes the wrong way: Luis Felipe Dias takes control, lands strikes, sets the pace. Duclos takes the hits. You know the usual outcome of such a round.
It didn’t happen. At 4:35, a left counter lands and the Brazilian collapses. KO in the first round, for an UFC debut that bookmakers and most observers expected to go the other way.
The check followed: $25,000 finish bonus, in a night that handed out four. Then the mic. His post-fight press conference, vengeful and openly patriotic, made almost as much noise as the KO. At Project X Paris, we know this register: it’s that of a guy who heard everything said about him for two years.
A must-see: the main event of the night, Salahdine Parnasse’s KO over Dan Hooker (RMC Sport Combat).
The next step: a ranking, a division, two Frenchmen
At 31 years old, Duclos enters a middleweight division where France has only one other representative: Nassourdine Imavov. The contrast is clear. One is established near the top of the rankings, the other has just earned the right to claim a spot.
No target announced yet, and that’s consistent. The plan is simple: keep finishing fights, and disprove the lucky regional label. Out of eleven pro wins, he left only two to the judges. The argument speaks for itself.
THE COUNTER WAS READY
Seven years taking hits, two doors slammed shut, five wins to rebuild. Duclos waited 4:35 to land the only strike that really mattered. The middleweight division hasn’t yet seen what he keeps in reserve.
