UFC Fighter Allan Nascimento Dies at 34

Allan Nascimento, a 34-year-old Brazilian fighter who competed in the UFC, was pronounced dead on Monday after being found unresponsive in his sleep, according to a statement from the promotion. The UFC said medical personnel determined the cause was an apparent heart attack.

Nascimento began his mixed-martial-arts career in Brazil in 2011, amassing a 17-4 record before appearing on Dana White’s Contender Series in 2018. Although he lost a split decision to Raulian Paiva on the series, he was signed to the UFC in 2021. During his tenure he earned victories over Cody Durden, Jafel Filho, Carlos Hernandez and Jake Hadley, and suffered defeats to Tagir Ulanbekov and Mitch Raposo. He received two Performance of the Night bonuses.

His most recent bout was a split-decision loss to Mitch Raposo at UFC Vegas 119 in June.
