Jack Marshman

Jack Marshman is a retired Welsh mixed martial artist and former British paratrooper who fought his way from regional promotions to the UFC with a professional record of 23-10. Born in Abertillery, Wales, in 1989, Marshman was introduced to MMA at age 15 by his coach Richard Shore and became instantly hooked. He went on to serve a full decade as a Lance Corporal in the 3rd Battalion of the Parachute Regiment, where he was deployed to Afghanistan - an experience he credited with building the physical and mental toughness that powered his fighting career. Before joining the UFC, Marshman won middleweight titles in both Cage Warriors and BAMMA, establishing himself as a formidable regional competitor with a 20-5 record and making history in November 2016 as the first Welsh fighter ever signed to the Octagon.

In the UFC, Marshman fought primarily as a middleweight and showcased a boxing-heavy striking style backed by genuine knockout power, finishing 13 of his career victories by KO or TKO. His debut was a statement, when he stopped Magnus Cedenblal via TKO in the second round and earned a Performance of the Night bonus. However, the level jump proved steep. He ran into elite-level footwork and technique when he faced Thiago Santos in February 2017, who dropped him with a spinning heel kick and finished the job with strikes. Over his final years in the UFC, Marshman faced an uphill road against top-10 competition, losing to Edmen Shahbazyan (submission, R1) and Sean Strickland (unanimous decision) among others, finishing his Octagon career with a 3-5 record.

Marshman's time in the UFC was also marked by weight-cut struggles: he came in 2 pounds overweight for his 2019 bout with John Phillips and again 1.5 pounds heavy against Strickland in 2020, both times proceeding at catchweight and absorbing fines. He even received a formal military reprimand for fighting during the Phillips fight week against orders. After his final UFC outing in October 2020, Marshman transitioned to bare-knuckle boxing but retired from competition in May 2026 following a loss to Danny Mitchell, reflecting in a heartfelt statement on his multi-sport journey and his newfound priorities: family, faith, and sobriety. Fans who followed Marshman respected his grit, his striking power, and his honest, no-excuses approach both in and out of the cage.
