Antonio Cesar Vs. Viet Anh Do, Pedro Dantas Vs. Adlan Umarov MMA Fights Booked For ONE Fight Night 50
ONE Championship has revealed two more exciting MMA bouts for ONE Fight Night 50 on Prime Video, the final show of the 2026 calendar, and both matchups feature fighters with serious finishing power.
Brazil’s Antonio “The Flash” Cesar will face Kiwi-Vietnamese rising star Viet Anh Do in a flyweight MMA clash, while Brazilian striker Pedro “Guerreiro” Dantas will welcome undefeated Kazakh promotional newcomer Adlan Umarov in a featherweight MMA showdown.
This highly anticipated event goes down live in U.S. primetime from the historic Lumpinee Stadium in Bangkok, Thailand, on Friday, December 18.
Cesar Owns 10-Fight Win Streak, Do Has Perfect Finishing Rate
Cesar has enjoyed a flawless start to his ONE Championship career.
The 22-year-old Manaus resident, who trains out of Fight Academy and Associação Maquiné, made a decisive promotional debut with a commanding unanimous decision victory over Filipino fan-favorite Lito “Thunder Kid” Adiwang at ONE Fight Night 45 this past July.
Cesar followed that up by handing Joshua “Flyin Hawaiian” Perreira his first career loss, stopping him via first-round TKO at ONE Fight Night 48 last month.
The Brazilian carries a 15-2 record, a 2-0 ONE Championship slate, and a 10-fight winning streak into his third promotional appearance. A fluid, mobile striker with a taekwondo background who switches stances, he also brings a BJJ game to the contest that makes him a threat on the ground.

Do, however, presents a difficult test for a man who seems to be in peak form.
The 29-year-old, who was born in Vietnam and raised in New Zealand, trains at Auckland MMA and Oliver MMA South Auckland. He is 7-0 as a pro with a 100 percent finishing rate and relies on heavy hands to score knockouts.
Do earned a life-changing US$100,000 contract in May 2026 after rattling off three stoppage victories on the ONE Friday Fights circuit. Then, he earned a highlight-reel finish in his U.S. primetime debut, stopping Davi “Ajuricaba” Brandão via third-round TKO at ONE Fight Night 46 in August.
Both men are climbing their way toward the ONE Flyweight MMA World Championship, and a statement performance could punch the winner’s ticket to a title opportunity.
Dantas Looks To Build Momentum Against Undefeated Newcomer
Dantas, who holds a 7-1 MMA career record, had a rocky start to life in the world’s largest martial arts organization.
The Brazilian known as “Guerreiro” made his promotional debut in July 2025 as an undefeated fighter, but he dropped a close decision to Ibragim Dauev. His kickboxing battle with top contender Mohammad Siasarani in January 2026 ended the same way.
However, the 23-year-old Fortaleza native bounced back in epic fashion at ONE Fight Night 47 this past September, as he dominated fellow South American Hector “La Arana” Almonacid to take a unanimous decision victory.
Now, the second-generation MMA fighter will look to build off that performance to string together some momentum toward the divisional gold.

Standing across from him will be Umarov, an unbeaten warrior who will make his ONE Championship debut with a 4-0 record and a perfect 100 percent finishing rate.
The Kazakh will be looking to make an instant impact on the global stage, and a win over Dantas would do exactly that.
Every one of Umarov’s four professional wins has ended inside the distance, one via TKO and three more via rear-naked choke. That run has made him one of the more intriguing newcomers on the ONE Fight Night 50 card.
For the undefeated Kazakh, this matchup is a chance to prove that his finishing instincts translate brilliantly on the biggest platform in the martial arts world.
