MONDAY — UFC fighter allan nascimento has died at the age of 34, the promotion said, after he was found unresponsive at home on Monday morning following an apparent heart attack in his sleep.

UFC tribute to allan nascimento
In a statement, the UFC said: “This morning, Monday, August 3, our beloved fighter and exemplary flyweight Allan Nascimento was found unresponsive after suffering an apparent heart attack in his sleep.
“Despite the efforts of the responding medical team, he was pronounced deceased at the scene.”
The promotion added: “Our thoughts and deepest condolences are with Allan’s family, friends, team-mates, and loved ones during this incredibly difficult time.”
Nascimento had been with the UFC since 2021 and fought six times in the Octagon, building a 4-2 record in the promotion. Across his MMA career, he won 22 of 29 bouts, with 16 of those wins coming by submission, according to the UFC tribute posted on its site.
His last fight came in June, when he lost to Mitch Raposo in Las Vegas by split decision. That detail matters because it places the death close to an active stretch in his career, not at its end. He was still part of the UFC roster and had remained a visible presence around the Top 15 doorstep, according to the tribute.
Reactions from Chute Boxe and Charles Oliveira
Chute Boxe, the Brazilian team where Nascimento trained under coach Diego Lima, called him a “warrior, friend, dedicated competitor and extraordinary human being” in a post on Instagram. The team said he had earned “the respect and admiration of all who had the privilege of knowing him.”
The same tribute said: “Allan inspired on and off the mats with his determination, humility, respect and fighting spirit.”
Former UFC champion Charles Oliveira, who trained alongside Nascimento, posted a personal message on Instagram and called him a brother. “Today I lost a brother that the fight game gave me,” Oliveira wrote.
“Thank you for always being by my side, for sharing the mats and the corner,” he said. “I have nothing but gratitude for having you with me in training, in the corner, and just hanging out. I love you, man; you're a legend.”
Oliveira added: “Thank you for the wonderful journey, brother. You were always an incredible person, and today is an extremely sad day for all of us at Chute Boxe. I will carry you in my heart forever, champion.”
The loss also hit a training room that included other notable names, with the BBC noting Nascimento trained at Chute Boxe under Diego Lima and worked alongside Oliveira and UFC lightweight Elves Brener. For the fight community, the immediate impact is blunt: a current UFC flyweight, still active this year, is gone at 34, and the tributes now define the next days around the Octagon.
The UFC said Nascimento was “a skilled competitor and consummate professional.” It closed its tribute with condolences to his family, the Chute Boxe Diego Lima team, and everyone affected by “this sudden, heartbreaking loss.”
