During his competitive time in professional mixed martial arts (MMA), former UFC middleweight contender Chael Sonnen used his widely-herladed promotional abilities to raise his profile as well as those of his fights. Now retired from MMA, he's still putting those skills to use, but in a different if slightly related context.
Sonnen is officially becoming a promoter as he launches 'Submission Underground', a submission grappling event based on the superfights model. The first event is set to take place on July 17 at the Roseland Ballroom in Portland, Oregon and will air exclusively on FloCombat.
