Piper was a guy who was basically in a top role his entire career with the NWA and WWF, though he was smaller than someone who Vince McMahon would consider for a World championship role. But, he made himself a giant star with his personality and charisma, including a legendary feud with Hulk Hogan that spawned the “Rock N Wrestling” phenomenon. It was pretty much inevitable that people outside of the business would try to lure him away, and that’s exactly what happened in 1987, as he signed for a series of starring roles in B-movies, most famously John Carpenter’s "They Live" — you know, the movie about the sunglasses that reveal hidden aliens and the bit about the bubblegum . Piper had a memorable feud with “Adorable” Adrian Adonis as a part of his babyface turn, and then announced his retirement following a win over Adonis at "WrestleMania III."
Silva faced Mark Hunt on December 7, 2013 at UFC Fight Night 33 in the main event.  It was a back-and-forth affair that saw both men trade the advantage over five full rounds. The end result was a majority draw (48–47 Hunt, 47–47, and 47–47).  Post-fight, Dana White said the bout won Fight of the Night and, despite the draw result, both men would receive their win bonuses.  Silva forfeited his win money and $50,000 Fight of the Night bonus to Hunt after failing a post-fight test for elevated testosterone (he had been undergoing UFC-approved testosterone replacement therapy ). He was suspended for nine months, retroactive to the date of the fight.
