The mixed martial arts world is mourning the tragic loss of one of its most dedicated flyweight competitors. Allan Nascimento, the Brazilian fighter known as “Puro Osso” (All Bones), passed away on August 3, 2026, at the age of 34 after suffering an apparent heart attack in his sleep. The UFC confirmed his passing in a statement, sending shockwaves through the fighting community and leaving teammates, fans, and fellow athletes in disbelief.
Nascimento’s final chapter in the Octagon was written just weeks before his untimely death. His last fight took place on June 20, 2026, at UFC Fight Night 119 in Las Vegas. In a closely contested bout, he faced Mitch Raposo and lost via a split decision. Following the defeat, he displayed the resilience and character that defined his career, writing on Instagram, “Unfortunately, the win didn’t come this time—a loss via split decision—but I leave with my head held high, knowing I gave it my all in there. Losses also teach, strengthen, and are part of the journey”. Unbeknownst to everyone, this would be the final walk to the Octagon for the beloved Brazilian.

A black belt in Brazilian jiu-jitsu, 15 of his 22 career wins came by submission. His grappling prowess earned him two prestigious “Performance of the Night” bonuses. The first came in January 2023 when he submitted Carlos Hernandez with a first-round rear-naked choke. The second followed in November 2025 with a stunning second-round anaconda choke against Cody Durden. He was a long-time member of the renowned Chute Boxe Diego Lima gym, training alongside former UFC lightweight champion Charles Oliveira, who mourned him as a brother.
The Financial Footprint: Net Worth, Contract & Career Earnings
While specific details regarding Allan Nascimento’s total career earnings and net worth have not been publicly disclosed by his management, some data provides insight into his compensation as a UFC athlete. The UFC’s pay structure is complex, with fighters earning a combination of show money, win bonuses, performance bonuses, and promotional compliance pay. Nascimento’s final disclosed payout was for his last fight at UFC Fight Night 119, where he received $6,000 in UFC Promotional Guidelines Compliance pay. This tier of payment is typically awarded to fighters with 6-10 UFC bouts, which aligns with his six appearances in the promotion.

His most significant disclosed earnings came from the two $50,000 Performance of the Night bonuses he earned, which would have substantially boosted his income for those events. However, details regarding his base salary for each fight, win bonuses, and any other sponsorship revenue remain private. While his official net worth was never made public, it is estimated to have been in the low six-figure range, typical for a talented but non-champion UFC fighter. His legacy, however, is not defined by his financial worth but by the heart and skill he brought to every fight. He leaves behind a professional record of 22 wins and 7 losses, having fought 29 times and winning the vast majority of his bouts.
