UFC and Chute Boxe pay tribute after flyweight Allan Nascimento
dies at age 34
The UFC posted a condolence message on social media.
“This morning, Monday, Aug. 3, our beloved flyweight fighter, 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. Our thoughts
and deepest condolences are with Allan’s family, friends,
teammates, and loved ones during this incredibly difficult
time.”
His team,
Chute Boxe, also took to social media to share a message.
“Today, our team loses much more than an athlete; we have lost a
warrior, a friend, a dedicated competitor, and an extraordinary
human being who earned the respect and admiration of all who had
the privilege of knowing him. Allan inspired on and off the mats
with his determination, humility, respect and fighting spirit.”
Nascimento originally started competing in muay thai in 2008. Due
to his skinny frame, he earned the nickname “Puro Osso,” meaning
skin and bones. Nascimento transitioned to MMA soon after and paid
his dues on the regional circuit for a decade before making his UFC
debut in 2021. The 34-year-old went 4-2 in the UFC and was coming
off a narrow split decision loss against Mitch
Raposo in June.
