Ronaldo “Jacare” Souza retired from mixed arts competition in 2021 following a four fight losing streak that was capped off by his first ever submission defeat to Andre Muniz via armbar.
Jacare started his MMA journey in 2003 in the midst of a jiu-jitsu career that saw the Brazilian win CBJJ and ADCC titles with and without the gi. His competitive success in the submission grappling realm translated beautifully to MMA, where Jacare scored 14 career submissions out of 26 wins and rarely lost a grappling exchange during a fight. When Jacare announced his retirement in August 2021, he hinted at a return to jiu-jitsu competition, telling Combate that he felt he retired too young from the sport where he made his name.
