Nascimento was found unresponsive after suffering an apparent heart attack in his sleep, according to a statement released by the organization.
Despite efforts by emergency responders, he was pronounced dead at the scene, the UFC said.
The Brazilian compiled a 22-7 professional record and went 4-2 inside the Octagon, with 15 of his 22 career victories coming by submission.
Nascimento earned his first Performance of the Night bonus by submitting Hernandez with a first-round rear-naked choke in January 2023, then added a second in November 2025 with a second-round anaconda choke against Durden.
Nascimento spent more than a decade pursuing his UFC dream before emerging as one of the promotion’s rising flyweight contenders.
