UFC flyweight Allan Nascimento died on Monday at age 34 after suffering an apparent heart attack in his sleep. The UFC announced the news on X, stating that he was found unresponsive and pronounced deceased at the scene by responding medical professionals. ‘Our thoughts and deepest condolences are with Allan’s family, friends, teammates, and loved ones during this incredibly difficult time,’ the UFC said in its message.

Professional Career and Record

Nascimento compiled a 22-7 professional record over the course of nearly 15 years as a professional MMA fighter. He turned pro in 2011 and won nine of his first 10 fights. A participant in Dana White’s Contender Series, where he lost to Raulian Paiva by split decision, Nascimento made his UFC debut in 2021, losing a split decision to Tagir Ulanbekov.

Following that loss, Nascimento secured four consecutive victories, defeating Jake Hadley, Carlos Hernandez, Jafel Filho, and Cody Durden. His wins over Hernandez and Durden earned him Performance of the Night honors. Nascimento’s winning streak came to an end in his most recent fight on June 20, when he lost a split decision to Mitch Raposo.

Reactions and Tributes

Allan Nascimento was a key training partner and friend to several prominent fighters, including Charles Oliveira and Elves Brener, at the Chute Boxe gym in São Paulo. His death has deeply affected the MMA community. Oliveira expressed his grief on social media, writing, ‘Today I have lost a brother that the sport gave me. Thank you for always being there, for sharing the mats and the corner with me.’

The UFC described Nascimento as a ‘beloved’ member of its roster. He was known for his grappling skills and Brazilian Jiu-Jitsu expertise, holding a black belt in the discipline. Nascimento trained under coach Diego Lima and was part of the Chute Boxe Academy, a well-known training ground for Brazilian MMA talent.

Final Fight and Legacy

Nascimento’s most recent appearance in the Octagon was on June 20 at UFC Fight Night 279 in Las Vegas, where he competed against Mitch Raposo. He lost the fight via split decision. Before his UFC career, Nascimento was known in the Brazilian MMA scene for his submissions and grappling prowess. His nickname, ‘Puro Osso’ (meaning ‘Haut und Knochen’ or ‘Skin and Bones’), reflected his lean, agile fighting style.

Colleagues and fans expressed shock and sorrow at the news of his passing. In a statement, the UFC reiterated its condolences, stating, ‘Our thoughts and our deepest sympathy are with Allans family, his friends, teammates, and everyone close to him in this incredibly difficult time.’
