6 WWE Superstars you didn't know also competed in MMA 

#1 Gentleman Jack Gallagher

Despite his comedy antics, Gallagher was a vicious fighter in Mixed Martial Arts

Jack Gallagher is a British pro wrestler on 205 Live and has entertained fans with his antics over the years. Throughout most of his stint with WWE, he has been primarily used as a comedy act – though he has still earned a reputation as a solid in-ring performer and though he's yet to hold the Cruiserweight title, is consistently considered one of the purple brand's top stars.

Before making pro wrestling his primary career focus, Gallagher had a couple of MMA bouts under the name Jack Claffey (his real name is Oliver Claffey). He finished his short-lived fighting career with a 2-0 record, making him the only undefeated fighter on this list.

Though Gallagher's MMA background hasn't been referenced on WWE TV to the same extent as Brock Lesnar or Ronda Rousey, the Gentleman has hinted to his past fights. When the UFC was in the hunt for a second opponent for CM Punk (who is 0-2), Gallagher said he would do it, since he had "two minutes to spare", a not so subtle dig at the Best in the World's poor UFC performance.
