Ken Shamrock never won a WWE World Championship during his tenure in the company in the late 1990s, but the UFC legend was tipped for big things at one point. “The World’s Most Dangerous Man” was arguably the most legitimate fighter on the roster having come from a successful mixed martial arts background, but he didn’t stick around long enough to turn that credibility into a main event run.
The sudden nature of Shamrock’s exit has always been a mystery among wrestling fans. He was only with the company for two years before he returned to MMA. After that, he returned to the squared circle when debuted in Total Nonstop Action in 2002, winning the vacant World Championship. However, citing Jim Ross on the latest edition of Grilling JR, Sportskeeda reports that his real reason for leaving was because he had unfinished business in the octagon.
