Richie “Boogeyman” Martinez Vs. Jake Shields Announced As Submission Underground 11 Co-Main Event

One of 10th Planet’s most celebrated athletes, Martinez made a name for himself with multiple impressive performances at EBI. Since then, he’s continued to raise eyebrows with his submission-heavy resume, and after a superfight win at Polaris 10 last year, he’ll be coming into his match with Shields hungry for another victory.
