The style
Sean "The One" Clancy Jr. is a 24-year-old welterweight out of Paisley, Scotland, training at Higher Level Martial Arts in Bathgate, who arrives in the UFC unbeaten and with every one of his nine professional wins coming by finish. He won the interim Cage Warriors welterweight title in December 2025 with a second-round knockout of Melvin van Suijdam in Newcastle, becoming one of Scotland's youngest champions, before a scheduled unification bout with Justin Burlinson fell through on fight day. He punched his UFC ticket on Dana White's Contender Series in August 2026, finishing Gary Balletto by TKO in round two for the seventh knockout finish of his career alongside two submissions and zero trips to the scorecards.
