Chael Sonnen may be done with mixed martial arts after retiring from active competition last week, but that doesn’t mean the bad guy is going away.
Just days after Sonnen announced he will be retiring from the UFC, the former light heavyweight and middleweight title contender has signed on to compete in the main event of the upcoming Metamoris 4 card on August 9 in Los Angeles. The news of the match was first reported on Twitter on Thursday.
Metamoris is a Brazilian Jiu-Jitsu promotion that puts on submission only matches with several notable names appearing on past cards including UFC heavyweight Brendan Schaub, Shinya Aoki and a who’s who list of grappling legends such as Eddie Bravo and Kron Gracie.
