João Zeferino

“The Brazilian Samurai”

João Zeferino connects jiu-jitsu teaching with an MMA career shaped by work on wrestling, striking and the demands of different weight classes.

Biography

João Zeferino's time at Roufusport involved teaching and learning. In a 2013 MMA Junkie interview, he recalled serving as head jiu-jitsu instructor during spells in 2009 and 2011, working with Anthony Pettis, Erik Koch and Ben Askren. Askren, in turn, helped strengthen his wrestling. Zeferino said Brazil remained his base because of family ties and the training partners and coaches available in Florianópolis. Born in Florianópolis in 1986, Zeferino began jiu-jitsu at sixteen. BJJ Heroes traces his path from Ataque Duplo in 2002, where he stayed through purple belt, to a year with Claudio Arrais from 2005, and then Alexandre de Souza's Gracie Barra team in 2006. He became a black belt under de Souza of Gracie Floripa. His preparation for MMA also included boxing, judo and yoga. His professional MMA debut came at Floripa Fight 1 on 26 November 2005, with a decision win over Bruno Amorim. He also continued competing in jiu-jitsu. At the 2010 Sul-Brasileiro, he took black-belt medium-heavyweight bronze and open-class silver for Gracie Florianópolis. Graciemag's report describes the open final against Moacir Mendes: Zeferino pulled half guard and swept to take the lead, but Mendes levelled the score, passed and added knee-on-belly points to win 7–2. A place on the UFC's May 2013 card became available while Zeferino was preparing for another fight. His managers, Alex Davis and Isaias Pele, put him forward on a seven-fight winning run. Rafael Natal, his opponent, was familiar from jiu-jitsu: Zeferino recalled beating him on points in a 2008 Brazilian championship semi-final at brown belt. This time Natal won the decision, at UFC on FX 8 on 18 May. Before his second UFC appearance that September, Zeferino told the promotion that the problem with his debut had been the three-week preparation, rather than nerves. For the next fight, he had worked on Muay Thai, conditioning and wrestling, bringing in wrestling partners and splitting sessions between Florianópolis and the Nitrix centre in Balneário Camboriú. Later that year he also taught how jiu-jitsu could be used in MMA: on 13 November, he delivered a seminar for participants in Udesc's Esportes de Contato extension programme at its Cefid centre in Florianópolis. At WSOF 25 in November 2015, submission grappling carried him through two rounds of a one-night lightweight tournament. He heel-hooked Brian Foster in the quarter-final and Jorge Patino in the semi-final. Foster returned to the bracket after Mike Ricci withdrew injured, setting up a rematch in the final. Zeferino lost that second encounter to strikes. Another title opportunity followed at welterweight: on 2 April 2016, Jon Fitch beat him by unanimous decision for the vacant WSOF championship. In his 2018 Sherdog interview, Zeferino described himself as a fighter who had matured slowly. He recalled Duke Roufus's advice that athletes developed at different rates. The Fitch fight had prompted more work on wrestling, which he identified as his weak area. He credited boxing coach Lenny Wilson and Muay Thai coach Jamie Crowder with progress in his striking, which he then felt had caught up with his grappling. Weight class was part of that reassessment. Having fought at middleweight and lightweight, he described the lightweight cut as difficult. Welterweight felt more comfortable, allowing him to eat better and concentrate on improvement. The Professional Fighters League seasons brought interruptions as well as opportunities. In a 2021 Combate interview, Zeferino recalled qualifying second for his first playoffs before a knee injury ended that opportunity. In 2019, he entered in the second regular-season round and won, but did not accumulate enough points to qualify. Ahead of Jason Ponet in June 2021, he described preparing one bout at a time. His film study had identified openings in Ponet's takedown defence and ground game. His later jiu-jitsu results span masters and adult divisions. At the 2023 Brazilian No-Gi Championship, he won Master 2 black-belt heavyweight and open-class gold representing Drava Jiu-Jitsu. His IBJJF record adds Master 2 no-gi heavyweight gold at the 2024 and 2025 Brazilian Nationals and the 2025 South American Championship, followed by silver in that division at the 2025 No-Gi Worlds. He also won adult black-belt no-gi heavyweight at the 2024 and 2025 Floripa Winter Open, and the adult open class at the 2024 Floripa Fall Open. In 2026, the Floripa Winter Open brought Master 2 super-heavyweight gold. MMA continued alongside those results: Sherdog records a unanimous-decision win over Raffael Cerqueira at Liga Monstro Combate 1 on 6 June 2026. Teaching remains visible through several academy settings. Renzo Gracie Middletown in New York offers members private lessons with Zeferino in gi and no-gi. AJP's club directory places João Zeferino Academy in Florianópolis and names him as the person in charge; his IBJJF athlete page also registers him with that academy. The BJJ in Paradise programme in Florianópolis advertises him as an instructor for private and group training, beginner and advanced options, no-gi sessions and Saturday open mats.
