- Matheus Araujo submitted Anderson Nascimento with a first-round rear-naked choke at Jungle Fight 149.
- The finish turned ugly when Araujo held the choke after Nascimento tapped and the referee tried to intervene.

- Members of both teams entered the cage before security and officials managed to stop the situation from escalating further.
- Araujo said afterward that the incident was fueled by personal comments made about his late mother during fight week.
The Jungle Fight 149 brawl did not begin with a wild punch, a bad scorecard, or a controversial stoppage. It began with something far more dangerous in grappling terms: a submission that should have ended cleanly, but didn’t.
Matheus Araujo beat Anderson Nascimento in the main event of Jungle Fight 149 in São Paulo, Brazil, securing a first-round rear-naked choke in the welterweight grand prix. On paper, that should have been a major tournament moment: a statement win, a semifinal ticket, and another step toward the Fight do Milhão prize.
Instead, the image everyone will remember is Araujo holding onto the choke after Nascimento tapped.
Footage from the bout showed Nascimento tapping multiple times as the referee moved in to separate the fighters. Araujo did not immediately release the hold. When he finally let go, he pushed Nascimento away with his feet, adding one last spark to an already burning moment.
Nascimento then got back up and landed punches while officials were still trying to control Araujo. Seconds later, members of both camps entered the cage, turning a submission finish into a near-brawl before the situation was contained.
For a promotion built on raw Brazilian MMA energy, Jungle Fight has seen plenty of chaos before. But this was different. This was not just heat after a fight. This was a post-submission ethics issue, and that is why the Jungle Fight 149 brawl hit so hard with grappling fans.

Why The Rear-Naked Choke Refusal Crossed MMA’s Brightest Line
There are many grey areas in MMA. Late shots happen. Fighters follow through on combinations after the bell. Adrenaline clouds judgment. Referees sometimes get there half a second too late.
But submissions are different.
In Jiu-Jitsu, No-Gi grappling, and MMA, the tap is sacred. It is the agreement that allows fighters to push submissions to the edge without turning every choke and joint lock into a career-altering injury risk.
The tap says, “I’m done.” The referee’s intervention says, “It’s over.” After that, there is no competitive reason to keep squeezing.
That is what made this rear-naked choke so uncomfortable to watch.
A rear-naked choke can render someone unconscious quickly when fully locked. Even when a fighter survives the initial squeeze, holding it after the tap adds unnecessary danger. MMA fans are used to violence; they are not used to seeing the basic safety contract of grappling ignored.
Araujo had already won. He had the back. He had the choke. He had the tap. The result was in his hands before the controversy even started.
That is also why Nascimento’s reaction, while not exactly a model of composure, was predictable. A fighter who believes he was held in a choke too long is not likely to stand up calmly and shake hands, especially after being shoved away with the feet.
The Jungle Fight 149 brawl was ugly, but the fuse was lit before the punches.
The Jungle Fight 149 Brawl That Exploded After The Tap
The bigger story is that this was not just a random main event gone sideways. Jungle Fight 149 was part of the Fight do Milhão welterweight grand prix, a tournament carrying a major cash prize and a clear pathway for fighters trying to break through in Brazilian MMA.
Araujo’s win moved him into the semifinals, where he is expected to face Fabricio Bakai. On the other side of the bracket, Ernane Pimenta and Guilherme Silva remain in the mix after earning knockout wins on the same card.
That tournament context matters because Araujo did not simply leave with a viral clip attached to his name. He left with his campaign still alive.
In pure performance terms, he looked sharp. He controlled the fight, created the finishing opportunity, and ended things inside the opening round. For a welterweight trying to win a high-stakes tournament, that should have been the story.
Instead, the Jungle Fight 149 brawl now follows him into the semifinals.
Every Araujo fight from here will carry the same question: can he keep the same intensity without letting emotion push him over the line? For a fighter nicknamed “The Monster,” that edge might be part of the brand. But in a tournament format, discipline matters as much as violence.
One mistake can cost a fight. One ugly moment can follow a fighter far longer than a highlight-reel finish.
Matheus Araujo Explains Why Emotions Boiled Over
After the fight, Araujo did not pretend the situation was normal. He admitted emotions played a role and pointed to comments he said Nascimento made about his late mother during the weigh-ins.
Things got a bit heated in the end and we stepped away from professionalism there. He talked about my mother at the weigh-ins and that’s something I held onto with resentment in my heart.
– Matheus Araujo –
That explanation gives the story context, but it does not erase the problem.
Trash talk is part of fight sports, and family insults have always been one of the cheapest ways to get under an opponent’s skin. If Araujo’s account is accurate, it explains why he carried so much anger into the cage.
But explanation is not the same as justification.
The cage is precisely where fighters are expected to control that anger. The referee’s job is to end the fight when one athlete can no longer intelligently defend or chooses to submit. Once that happens, personal resentment cannot become an excuse to keep a choke locked.
That is the uncomfortable balance in this story. Araujo may have had a real emotional reason to be furious. He may have felt disrespected in a deeply personal way. But the moment Nascimento tapped, the fight was over.
The rest is what turned a tournament win into a controversy.
Victory Turns Into Cage Chaos In São Paulo
The Jungle Fight 149 brawl will probably be replayed more than the actual finishing sequence, and that is the price of the moment.
For Araujo, the next fight is no longer just about advancing. It is about proving that he can perform under pressure without letting the emotional temperature hijack the result.
He already showed he can finish a former champion-level opponent quickly. Now he has to show he can keep control when the stakes and the noise rise again.
For Nascimento, the night ended in frustration, anger, and a loss that will be discussed less for the technical finish than for what happened afterward.
For Jungle Fight, the controversy brings attention, but not the clean kind. Viral chaos gets clicks. It also raises questions about fighter control, referee authority, and how quickly teams can be kept out of the cage when emotions explode.
The strange thing is that Araujo’s win was impressive enough without the extra drama. A first-round rear-naked choke in a major tournament main event should have been the perfect headline. Instead, the headline became the refusal to let go.
That is why the Jungle Fight 149 brawl will not disappear after one news cycle. It combines everything that makes combat sports irresistible and uncomfortable at the same time: skill, anger, revenge, danger, and the terrifying moment when a professional fight briefly stops looking professional.
