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

#3 Nathan Jones

Jones was taken out of his WrestleMania 19 match but appeared at the end to help The Undertaker win

Nathan Jones was an Australian professional wrestler who was part of the WWE roster from 2002 to 2003. His most memorable angle during his time with the company was when he served as The Undertaker’s protégé. After being pulled from the WrestleMania 19 tag team match with The Deadman against Big Show and Albert, the Aussie's career would never reach the same highs, and a random heel turn and alliance with Brock Lesnar later that year couldn't save it.

Jones abruptly quit WWE in 2003 after holding no titles in the company and lasting little over a year. The 6' 11" Aussie has since gone on to have an impressive career out of the ring and has appeared in several major motion pictures including WWE Studios' project The Condemned, Troy and Mad Max: Fury Road.

In 1997, Jones competed in his first and only professional MMA fight at Pride 1. The former WWE star took on sumo champion by the name of Koji Kitao. Kitao would end up winning the fight via submission, proving that though he may be successful on the silver screen, the Octagon isn't for him.
