Submission Underground finally makes its 2021 debut today with Submission Underground 21. The card is headlined by the Submission Underground king and men’s champion Mason Fowler defending his belt against another SUG mainstay in “The Boogeyman” Richie Martinez. Both Martinez and Fowler won their most recent bouts by armbar in regulation at SUG’s last event, Submission Underground 20.
The co-main event features the Submission Underground queen and women’s champion Amanda Loewen putting her belt on the line against UFC flyweight contender and women’s MMA pioneer Roxanne Modafferi. Loewen is undefeated in SUG, most recently defeating former UFC featherweight title challenger Felicia Spencer by armbar during regulation at Submission Underground 19.
