Jermall Charlo is 34-0. He is also 36 years old and has fought four times since September 2020, and on Thursday that number stopped looking like bad luck.
Charlo was pulled from his October 17 bout against Koen Mazoudier at The Cosmopolitan of Las Vegas after hurting himself in training camp, per Mike Coppinger of The Ring. The nature of the injury has not been disclosed. Jose Armando Resendiz steps in on roughly 10 days’ notice for the 10-round super middleweight fight, which opens the DAZN on TNT card headlined by Sebastian Fundora’s WBC junior middleweight defense against Ermal Hadribeaj.
This is the second time Charlo has failed to make this exact fight. He was booked against Mazoudier in July on the Tim Tszyu-Errol Spence undercard in Australia and did not get there because of a visa issue.
Four Fights in Six Years
Run the ledger. Charlo beat Sergiy Derevyanchenko in September 2020, beat Juan Macias Montiel in June 2021, then disappeared for 29 months before a 2023 catchweight win over Jose Benavidez Jr. He was stripped of the WBC middleweight title he had held since 2019 in May 2024, and his last appearance was May 31, 2025, when he dropped Thomas LaManna three times and got the stoppage in the sixth.
That one was supposed to be the restart. It ended an 18-month layoff and put him back at 168 pounds with a regional belt and a clear runway. Seventeen months later he has not fought again.
The record is still perfect, and that is the problem. Nobody can evaluate what Charlo has left because there is nothing recent to evaluate. He turns 37 in May. A former two-division champion with no losses should be an attraction in a loaded super middleweight division, and instead he is a name that keeps falling off cards.
Resendiz Is the Real Winner Here
The replacement is more interesting than the man he replaced. Resendiz is 27, from Nayarit, Mexico, and carries a 16-3 record with 11 knockouts. He pulled off one of 2025’s biggest upsets, taking a split decision over Caleb Plant on May 31 to win the WBA super middleweight belt, then lost it to Jaime Munguia by unanimous decision on May 2 of this year.
So he gets a short-notice fight in Las Vegas on a televised card against a 30-year-old Australian making his United States debut. Mazoudier is 16-4-1 with six knockouts, has won four straight since losing to Nikita Tszyu in 2024, and most recently outpointed Sam Beck on August 26.
Resendiz has fought twice in two years at the top of the division. Mazoudier has never been in a ring on American television. One of them walks out of the Cosmopolitan with momentum he did not have on Wednesday.
What It Means for Charlo
Honestly, it means the comeback is on hold indefinitely, and nobody has said otherwise. No new date has been announced and no timeline for his recovery has been reported. The Fundora card moves on without him, as cards have for most of the last six years.
An unbeaten record at 36 is only worth something if you cash it. Charlo keeps running out of chances to try.
