Yuneisy Duben

Venezuela

Still searching for first UFC win
FlyweightUFC
June 6, 2026
Duben lost to Jeisla Chaves via split decision (28-29, 29-28, 28-29) at UFC Fight Night on Saturday in Las Vegas.
ANALYSIS
Simply put, there's no way Duben won this fight despite the scorecard Tony Weeks submitted. That said, she wasn't blown out by any means. The numbers were close, and Duben was able to reverse position on Chaves to win Round 3, but she pretty clearly was down 20-18 entering the final frame. Already 29 years old and with all of eight professional fights under her belt, Duben has lost both of her official UFC appearances after joining the roster following a shocking 73-second knockout win over Shannon Clark on Dana White's Contender Series back in September 2024.

Sophomore effort upcoming
FlyweightUFC
March 19, 2026
Duben will fight Jeisla Chaves at UFC Fight Night 278 on June 6 in Las Vegas, Marcel Dorff of Eurosport.nl reports.
ANALYSIS
Duben shocked the MMA world after picking up a knockout victory as a heavy underdog on the Contender Series in 2024, but seemed overmatched by Carli Judice in her UFC debut last year. She will step into the cage with another Contender Series alum in Chaves, who is tough but took a considerable amount of damage before getting her hand raised on the show. Duben was pulled from a bout against Kennedy Freeman for undisclosed reasons in August, but seems to be healthy and ready to get back to action.
Withdraws from UFC Paris

August 5, 2025
Duben has withdrawn from UFC Fight Night 258 in Paris on Sep. 2 due to undisclosed reasons, Nolan King of MMAJunkie.com reports.
ANALYSIS
The reasons behind Duben's withdrawal are unclear, but the Venezuela native won't step into the octagon. She was looking to build confidence after losing to Carli Judice via TKO in her UFC debut on March 15. It's unclear when she'll be able to fight again, but in the meantime, Kennedy Freeman will have to search for a new opponent for the card to be held this September.
Second UFC bout scheduled

Duben will take on Kennedy Freeman in a flyweight bout at UFC Paris on Sept. 6, per Marcel Dorff of Eurosport.nl.
ANALYSIS
Duben is coming off a non-competitive showing in her UFC debut, falling quickly to Carli Judice in the first round of a fight in March. She'll get another shot with the promotion against a newcomer in Freeman, one of the best pound-for-pound female fighters in the United Kingdom.
Not competitive in UFC debut
FlyweightUFC
March 15, 2025
Duben lost to Carli Judice via TKO (strikes) at 1:40 of Round 1 at UFC Fight Night on Saturday in Las Vegas.
ANALYSIS
Responsible for what was likely the biggest upset in the history of Dana White's Contender Series with a 73-second knockout win over Shannon Clark last September, Duben made her official UFC debut here, and it didn't go well. Facing an opponent with an 0-2 career record with the company and all of five pro bouts under her belt entering the evening, Duben ate a head kick from Judice a little less than two minutes in and was essentially finished on the spot. A few follow-up shots later and referee Mark Smith was stepping in. The Clark result seems like a massive fluke at this point, and Duben would likely be fortunate to remain on the roster more than a couple more fights.
Official debut scheduled
FlyweightUFC
December 26, 2024
Duben will take on Carli Judice in a flyweight matchup at the UFC event scheduled for March 15, Nolan King of USA Today reports.
ANALYSIS
Duben picked up her UFC contract via Contender Series with a massive knockout as a sizable underdog, and now she has an official debut scheduled. Her opponent is another Contender Series product in Judice, who actually lost on the show and got an opportunity nonetheless, with both defeats of the split-decision variety. Duben will concede three inches in both height and reach to her opponent.
