Born on March 30, 1992, in Belford Roxo, Rio de Janeiro, Brazil, he has built a reputation as one of the most exciting finishers in the division since joining the promotion in 2018. As of August 26, 2025, he is ranked number 12 in the UFC light heavyweight rankings.

Early Life and Background
Walker Johnny Silva Barra de Souza was born on March 30, 1992, in Belford Roxo, a municipality in the state of Rio de Janeiro, Brazil. Growing up in Brazil, he was introduced to martial arts at a young age and developed the athletic foundation that would later define his professional career. Belford Roxo, located in the Baixada Fluminense region, provided the backdrop for his formative years and early training in combat sports.
He is the older half-brother of Valter Walker, a fellow UFC fighter who competes in the heavyweight division, giving the family a notable presence in mixed martial arts. The brothers share a Brazilian heritage and a commitment to the sport, and Valter’s own UFC career reflects the fighting pedigree established within the family. Walker has spoken in the past about his family ties and the role his Brazilian roots have played in shaping his approach to competition.
Path to MMA
Walker made his professional mixed martial arts debut in December 2013, beginning a journey that would carry him from regional Brazilian shows to the largest MMA promotion in the world. Over the next four years, he fought primarily in his native country and posted a record of ten wins against three losses, with every one of his victories coming by way of stoppage. That finishing rate quickly caught the attention of international promotions.
After his initial run in Brazil, Walker received an offer from a Scottish businessman to train overseas and made the move to Scotland. However, the arrangement did not work out, and he left after a month without receiving pay. In early 2018, he relocated to England, where he fought for various promotions and added three more wins to his record. Those performances earned him a coveted spot on Dana White’s Contender Series in August 2018, where a victory over Henrique da Silva via unanimous decision secured him a place on the UFC roster.
Johnny Walker Career
Early Career (2013-2018)
Walker’s early professional years were spent largely in his native Brazil, where he developed a reputation as a fast and dangerous finisher. Between 2013 and 2017, he competed on the regional circuit and for Jungle Fight, racking up a 10-3 record with all victories coming inside the distance. His finishing instincts and physical gifts set him apart from his peers during this developmental phase.
His time abroad began with a brief and unsuccessful stint in Scotland before he settled in England in early 2018. Three additional wins in the English circuit, combined with his dynamic style, brought him to the attention of UFC matchmakers. That summer, he earned his shot on Dana White’s Contender Series, where his unanimous decision victory over Henrique da Silva officially launched his UFC career.
UFC Breakthrough (2018-2019)
Walker made his UFC promotional debut on November 17, 2018, at UFC Fight Night 140 against Khalil Rountree Jr. and immediately announced his arrival with a first-round knockout. The performance earned him his first Performance of the Night bonus award and signaled the arrival of a new contender in the light heavyweight division. He followed that with an even quicker finish, knocking out Justin Ledet just 15 seconds into their February 2019 bout at UFC Fight Night 144, collecting a second consecutive Performance of the Night bonus.
A short-notice replacement for an injured Ovince Saint Preux, Walker faced Misha Cirkunov at UFC 235 in March 2019 and won by technical knockout in the first round, marking his third straight Performance of the Night bonus. However, his meteoric rise was halted at UFC 244 in November 2019, when Corey Anderson stopped him via technical knockout in the opening round. The loss was a setback, but Walker remained one of the most talked-about athletes in the division.
Tristar Gym Era (2020-2024)
Following his setback against Anderson, Walker trained out of Tristar Gym between 2020 and 2024.

Subsequent outings were mixed. A scheduled bout with Jimmy Crute at UFC 260 was canceled due to a chest injury, and he dropped a unanimous decision to Thiago Santos at UFC Fight Night 193 in October 2021. He also suffered a first-round knockout loss to Jamahal Hill in February 2022. He answered back with a first-round rear-naked choke of Ion Cuțelaba at UFC 279 in September 2022, earning his fourth Performance of the Night bonus. Wins over Paul Craig and Anthony Smith in 2023 were followed by a controversial no-contest with Magomed Ankalaev at UFC 294 in October 2023 and a knockout loss in their rebooking at UFC Fight Night 234 in January 2024. A first-round knockout defeat to Volkan Oezdemir at UFC on ABC 6 in June 2024 closed out his Tristar chapter.
SBG Ireland Era (2024-Present)
Walker now trains out of SBG Ireland and is based in Dublin. He was scheduled to face Bogdan Guskov at UFC 311 in January 2025 but withdrew due to injury.

He returned to action in the main event of UFC Fight Night 257 on August 23, 2025, defeating Zhang Mingyang by technical knockout via leg kicks and punches in the second round, a performance that earned him another Performance of the Night bonus.
