10 WWE Wrestlers Who Came From Other Sports

10. Wade Barrett - Bare Knuckle Boxing

England's Wade Barrett was sometimes accused of practicing a grappling style not befitting of his 6'7" frame, which is somewhat surprising when you learn about his background as a legitimate fighter. The one-time Nexus leader was a star on Europe's bare knuckle boxing scene before he turned his hand to professional wrestling in 2004.

Bare knuckle boxing is rarely shown live on Sky Sports One, which makes gauging Barrett's level of success a difficult task. What we do know is that he was good enough to graduate to the continental stage, having initially began fighting on the mean streets of Liverpool. To be fair, though, the Brit was floored by a single slap from Wayne Rooney, so perhaps we shouldn't get too carried away.
