#9 Oliver Claffey (Jack Gallagher) (2-0)
WWE 205 Live superstar Jack Gallagher had a brief stint in fighting before debuting for the company during the 2016 Cruiserweight Classic tournament, according to ESPN.
He trained in Brazilian Ju-Jitsu, kickboxing and boxing for eight years (while also honing his pro-wrestling craft in the UK indie scene) and picked up a 2-0 amateur record with two first-round submissions.
"The Extraordinary Gentleman" Gallagher, a native of Manchester, England, is the 63rd Ranked Amateur Lightweight in Great Britain and has credited the traditional World of Sport British wrestling style, which is heavy on the use of catch wrestling submissions, as the glue that binds his MMA and pro-wrestling experiences.
The style was popularized by English stars like NXT UK General Manager Johnny Saint and the legendary Billy Robinson. The late Robinson also straddled the fence between shoot and worked fights in his day, and helped trained Gallagher.
