#3 Matt Riddle (8-3)
The King of Bros, a trained student of Brazilian jiu-jitsu, won a single amateur fight before getting the chance to enter The Ultimate Fighter (TUF) house.
Making his official debut for the MMA promotion in 2008, he went on to win the overwhelming majority of his fights before being fired by the organization after testing positive for marijuana in two separate exams.
Nonetheless, Riddle is one of the highest ranked stars in UFC history for takedown defenses and strikes landed.
After brief runs in smaller MMA organizations like Bellator, Riddle began his pro-wrestling career in 2014.
He rapidly learned his new craft and became an in-demand name on the indie scene in 2015-17, performing for various promotions in the US and UK until finally signing a developmental deal with WWE in 2018.
He is currently being featured regularly on NXT weekly TV and recently won a high-profile match at Takeover: Phoenix on January 26.
