Calling all Universal (or Yearly) FloWrestling subscribers: Olympic medalists and collegiate All-Americans will be competing on FloWrestling brother site, FloCombat, this weekend.

FloSports and avid FloWrestling fan Chael Sonnen are excited to bring you Submission Underground LIVE from Portland, Oregon on July 17, starting at 3PM PDT.

Chael P. Sonnen wants to make grappling great again.

Featuring Stephen Abas, Jake Shields and a slew of MMA fighters like Chris Lytle, and Brazilian jiu-jitsu black-belts like Vinny Magalhães, the 13-fight card will use modified Eddie Bravo Invitational rules, which go as follows:
​
For eight minutes, a competitor can win only by scoring a submission. If there are no submissions, the match moves to an overtime period. The winner of a coin flip can elect to start the overtime period attacking from the back or from the "spiderweb" (arm bar) position. If one competitor scores a submission and his opponent does not, he is declared the winner. But if both competitors escape from submission attempts, the match moves to the next overtime round. After three overtime rounds, the competitor who escaped the quickest is declared the winner.
