Profile
Overview
Five of Jack Hermansson's UFC wins ended in the first round, and five of his eight losses ended by KO/TKO. Nothing in his career is quiet. The Swede is 11-8 in the UFC and 24-10-0 across all promotions, a welterweight out of Frontline Academy in Oslo who debuted in 2016. He is not a champion.
He has been a main-event fighter for years. He carries two straight losses into his next fight, both by first-round KO/TKO.
UFC Career
Hermansson debuted on September 2, 2016, with a unanimous decision over Scott Askham. His second fight ended in a submission loss to Cezar Ferreira, in round 2. He answered with first-round TKOs of Alex Nicholson and Brad Scott, then lost by KO/TKO to Thiago Santos at 4:59 of round 1.
The run that defines him came next: four straight wins, his longest streak. Thales Leites fell by TKO in round 3, Gerald Meerschaert and David Branch by first-round submission (Branch in 0:49), and then Ronaldo Souza by unanimous decision over five rounds. That is the one win over an elite opponent on his record.
The streak ended in a main event against Jared Cannonier, a TKO loss at 0:27 of round 2. Kelvin Gastelum came next, submitted in 1:18 of round 1. After that came three main events in a row against strong opponents: a five-round decision loss to Marvin Vettori, a split-decision loss to Sean Strickland, and a five-round decision win over Joe Pyfer in 2024. Wins over Edmen Shahbazyan and Chris Curtis by decision sit between them, and Roman Dolidze stopped him in round 2 in December 2022.
The most recent chapter is the hardest. Gregory Rodrigues finished him at 4:21 of round 1, and Myktybek Orolbai did it at 2:46 of round 1.
Two fights, two first-round stoppages.
Fighting Style
Jack Hermansson is a busy striker who is hard to hit. He throws and lands at a high volume, and he avoids strikes better than most fighters in the UFC. He is also very hard to take down, so opponents rarely get him to the mat.
He is more than a pure striker, though. Three of his 11 UFC wins came by submission, all in round 1. He doesn't hunt for submissions much, so those finishes read as opportunistic rather than a game plan.
His finishes come early. Of his six UFC finishes, five came in round 1 and the other in round 3. His losses tell a different story: five KO/TKO defeats, one submission, and two decisions. He is difficult to take down, but he has been easier to put away on the feet.
