A Swedish wrestler who built his MMA career at Frontline in Oslo and submitted jiu-jitsu black belt David Branch in 49 seconds in the UFC.

Biography

Jack Hermansson is a Swedish mixed martial artist, born in Uddevalla in 1988, who built his fighting career in Oslo at Frontline Academy. A wrestler first, he submitted David Branch, a Renzo Gracie jiu-jitsu black belt, in 49 seconds in the UFC in March 2019, using a guillotine that Frontline's jiu-jitsu coach had shown him years earlier. Wrestling in Uddevalla Hermansson has written that of all the sports he tried as a boy in Uddevalla, wrestling was the only one he really loved. He started with Greco-Roman wrestling at about nine and stayed with the local club, Uddevalla Atletklubb, for ten years; he has described the club as something close to a family. He has also said that he wanted to do martial arts from early childhood and practiced moves taken from books and Bruce Lee films before he found MMA on the internet around 2006. Many observers saw him as a striker, but before the Branch fight MMA Viking pointed out that he had several hundred wrestling matches behind him. He said then that wrestling had once been the strongest part of his game but that the rest of his skills had since caught up with it. From Sweden to Oslo He began some Muay Thai and MMA training at a gym in Uddevalla at about 18, and he dates the start of his MMA training to 2008. Like many young Swedes, he moved west to Norway looking for work. He found a job as a substitute teacher outside Oslo and trained first with Ståle Nyang in Lørenskog, then with Mohsen Bahari at Frontline Academy, who introduced him to Joachim Hansen and his Team Hellboy. Hansen was one of Hermansson's idols, and he has named him among his heroes alongside Alexander Gustafsson and Bruce Lee. A short return to Uddevalla ended without a job, and he went back to Oslo to work in a pet shop. When Team Hellboy later moved its training to Frontline Academy, some members left for other gyms or opened their own; Hermansson stayed with the Frontline pro team, the team he says he represents whenever he fights. He has written that he represents both Sweden, the country he was born in, and Norway, where he made his home and his career, and that he identifies with Swedes and Norwegians alike. The jiu-jitsu room at Frontline Recommending the academy to other fighters in 2013, Hermansson pointed to its many Brazilian jiu-jitsu black belts and to separate classes in MMA, jiu-jitsu and Thai boxing at levels from beginner to professional. The academy's head coach at the time, Eduardo "Teta" Rios, had received all of his belts from Ricardo Libório and followed him to the Carlson Gracie Academy and later to Libório's own gym. By 2019 Hermansson's own website listed Rios as his jiu-jitsu and MMA coach, with Bahari as his MMA coach. In a 2019 interview with Nettavisen, Hermansson traced his guillotine back to Rios. As he remembered it, Rios showed him a version of the choke in what was probably their first grappling session together. Years went by before Hermansson tried it himself. Once it started working in training, he kept going back to it until he trusted it enough to use it in a fight. MMA media have given his variation its own name, the "Jokertine", combining the choke with his nickname, "The Joker", which he says came from always having a smile on his face. He has also tested his grappling without strikes. In March 2016, while he held the Cage Warriors middleweight title, he took a superfight at the second Oslo Submission Series, a submission-only event run under EBI rules at Chateau Neuf in Oslo, and beat the Norwegian black belt Christopher Hermanstad with an armbar in overtime. In November 2021 he wrestled fellow UFC fighter Khamzat Chimaev in the main event of Bulldog Fight Night 9 in Gothenburg, a match Chimaev won clearly. Asked by the UFC for his favorite grappling technique, Hermansson named the heel hook. Titles in Europe His professional career began in 2010 with an East Coast Fight Factory title fight against the champion, Chris Greig. He recalls that Joachim Hansen told him about the bout, and he stopped Greig in the third round. He signed with Bellator in 2012 and lost both of his fights there, the first on a split decision to Daniel Vizcaya and the second to a triangle choke from Jason Butcher; by his own account he had been too eager after scoring a takedown. Back on the European circuit, he won the vacant Cage Warriors middleweight title in June 2014, submitting Norman Paraisy in round four with a rear-naked choke. His first defense came against Deyan Topalski, whom he took down early, and a second followed in April 2016. In August 2015 he also won the vacant Warrior Fight Series middleweight title. Against Karlos Vémola he won with a first-round armbar, the first fight he had finished from his back. By the time of his UFC debut he held the middleweight belts of East Coast Fight Factory, Warrior Fight Series and Cage Warriors. The titles changed little in his daily life. As Cage Warriors champion in early 2015 he still worked part-time in the pet shop and taught some classes at the club, and he told MMA Viking that his finances were far from secure. He also spoke about Norway's ban on combat sports that allow knockouts, which left the amateurs he coached struggling to find and pay for fights abroad, and said he hoped the new Norwegian MMA federation would get the sport legalized. The UFC The UFC announced his signing on 31 May 2016, and he won his debut on 3 September 2016 by unanimous decision over Scott Askham. In 2018 he beat Thales Leites, a fight he later told VG he had gone through with a rib that doctors believed had separated from the cartilage at his breastbone. He called the experience torture. In December 2018 he submitted Gerald Meerschaert with a guillotine in the first round. Three months later he met Branch: after bringing him down with a body-lock takedown, Hermansson trapped his head and one arm in the choke while Branch was on his hands and knees, then fell back to finish it. The win earned a Performance of the Night bonus and was MMA Viking's Nordic Submission of the Year for 2019. In April 2019 he beat Ronaldo "Jacare" Souza, then ranked in the division's top five, on a unanimous decision over five rounds in a short-notice main event. Hermansson has singled out the Branch and Souza fights as the ones that showed he belonged near the top. In July 2020 the heel hook paid off as well, when he submitted Kelvin Gastelum 78 seconds into the first round. The years that followed also brought defeats. He lost to Jared Cannonier in September 2019, to Marvin Vettori over five rounds in December 2020 and to Sean Strickland on a split decision in February 2022. A chronic back problem forced him out of a fight in 2023, the first withdrawal of his career. In February 2024 he beat Joe Pyfer on a five-round decision and afterwards called again for MMA to be legalized in Norway, saying a fight there would be a highlight of his career. After a first-round knockout loss to Gregory Rodrigues in June 2025, he moved down to welterweight for the first time for a November 2025 bout with Myktybek Orolbai in Doha, saying he wanted his remaining years in the sport to count. Orolbai stopped him in the first round, and his UFC profile lists his professional record as 24 wins and 10 losses. At Frontline, Hermansson is listed among the instructors as the head of the MMA pro team, and the academy presents him as its fighter in the UFC.
