Garry Tonon is one of the most feared men in professional grappling. He is a member of the notorious Danaher Death Squad and (among other accomplishments) holds a championship belt in three different weight classes in the Eddie Bravo Invitational.
Dean Lister is a second-degree BJJ black belt and mixed martial artist. He is a two-time ADCC gold medalist and the overwhelming majority of his 13 MMA wins have come by way of submission.
According to Martin, the match will be going down on January 29. It will probably air through FloGrappling.
