Chael Sonnen may have retired from MMA and is still facing potentially stiff penalties from the Nevada Athletic Commission following his recent drug test failures, but he’s still set to compete in a submission grappling match-up with BJJ ace Andre Galvao at the Metamoris 4 event on August 9th.
Below you can watch a special preview for the contest which will be the main event at the show and is set to be aired on pay-per-view for $20.
