The UFC community is mourning the loss of flyweight fighter Allan Nascimento, who has died at the age of 34. The Ultimate Fighting Championship announced Nascimento’s death on Monday, Aug. 3, saying the Brazilian fighter was found unresponsive after suffering an apparent heart attack in his sleep. Fellow UFC fighter Caio Borralho also remembered Nascimento as a respectful competitor with a positive attitude, saying he would be deeply missed. Born in Brazil, Nascimento built an impressive 17-4 record before earning a shot on Dana White’s Contender Series in 2018. Although he wasn’t immediately signed, he eventually joined the UFC roster in October 2021 and established himself as a talented flyweight contender.
