The UFC honored Allan Nascimento during Fight Night 284 following the flyweight's death at age 34 from an apparent heart attack in his sleep. Nascimento was a longtime member of Brazil's Chute Boxe Academy and a close friend and training partner of Charles Oliveira, Elves Brener, and other UFC fighters, leaving behind a wife and two children. His most recent outing was a split decision loss to Mitch Raposo in June, which snapped a four-fight winning streak that included two performance bonuses.
The UFC paused to honor the memory of Allan "Puro Osso" Nascimento during Fight Night 284, paying tribute to the Brazilian flyweight who passed away at age 34 from an apparent heart attack suffered in his sleep.
Nascimento compiled a professional record of 22 wins and 7 losses over a career defined by aggression and technical striking. Fighting out of Brazil's storied Chute Boxe Academy, he landed 3.2 significant strikes per minute at a 51 percent accuracy rate, while also mixing in a grappling dimension that produced nearly one submission attempt per 15 minutes. His most recent performance came in June, a split decision loss to Mitch Raposo that snapped a four-fight winning streak — a run that earned him two separate performance bonuses. He leaves behind a wife and two children.
The loss reverberated deeply through the Chute Boxe community. Lightweight contender Charles Oliveira, ranked third in his division at 36 years old and carrying a 37-11-0 record, was among those who counted Nascimento as a close friend and training partner. Fighter Elves Brener was also named among those mourning the loss of a teammate.
Raposo, the 27-year-old American who last shared the cage with Nascimento, holds an 11-3-0 record and fights out of Regiment Training Center.
Why it matters
- Nascimento's death is a sobering reminder of the health risks athletes can face outside competition, regardless of age or conditioning level.
- His four-fight winning streak and back-to-back performance bonuses had positioned him as a rising presence in the flyweight division before his passing.
- The tribute at Fight Night 284 reflects the tight-knit nature of the Chute Boxe community and the UFC's acknowledgment of fighters beyond their in-cage contributions.
