Rules and Divisions


SUB ONLY isn’t new. No Time Limit, Ref Decisions, Modified Rules, Draws. All have been explored, tested, and attempted in open invite tournaments.

With the Help of Eddie Bravo the Submission Challenge nearly 10 years ago,  began utilizing the EBI Overtime concept with modified Submissions for age and skill levels with incredible success.

Submission Only is Exciting. FUN. and a Positive Experience for Everyone.

EBI Rules Changed the Game. It reinvented Sub Only and continues to prove the superior Submission Only Ruleset. Submission Challenge is proud to be a pioneer and continual trailblazer of the rule set for Open Invite competition.

Ways a Match can be Won:

  • Win via Submission victory within regulation time.
  • Win in Overtime: victory by submission, fastest submission time, or fastest escape time.
  • Win by opponent disqualification.
  • Win via opponent forfeiture.

Submission is based upon physical tapping, a verbal tap, or yelling during a submission attempt. If an opponent must have the match stopped for any injury related incident or any other reason beyond control that does not warrant any disqualifications, the opponent will have 5 mins to return to the match or they will have to forfeit the match.

Eddie Bravo Invitational overtime rules. Any match whose regulation match time ends without a draw immediately moves into Overtime with break or time out unless deemed needed by referee. Any competitor who can not answer the call to immediately participate in the overtime round will be disqualified.

overtime round consists of Athletes choosing specific Dead-zones (The back or Spiderweb) from which the athletes will attack and defend submissions. Each competitor will get a try to attack for a submission. The competitor who can secure a submission their respective attacking overtime round will be the victor.

Based on athlete aggression and submission minded attacks the referee will choose a competitor to choose Offense or Defense at the beginning of the the 1st OT Round.

In Overtime there are two positions or Dead Zones available to attack and defend from.

Back Control with Seatbelt Grip 

Competitors will begin in a seated back control position upright with both hooks and a seat belt grip. The opponent may have their hands in place on the seat belt grip and chin tucked before ref begins the round. Once round begins the body triangle may be applied but not before.

Each position must have arms hooked, crook of elbow to crook of elbow. The opponent defending the position may have their arms in any defense configuration they desire. Below are samples of each position.

Submission Shootout

During the overtime rounds opponents are trying to submit or escape as fast as possible. Both opponents will have a chance to submit their opponent from a dead zone of their choosing or escape the deadzone their opponent chooses. The opponent who obtains a submission or the fastest submission in the Overtime round wins the match. In the regulation matches on a bracket fighters will have 1 single OT round to achieve a submission. In the finals (for 1st and 2nd Place) Fighters will have up to 3 overtime rounds to achieve a submission. In the event that escapes occur for both fighters, the combined fastest escape time will be the victor.

In OT the Goal is Submit your Opponent as fast as possible or Escape the Dead zone position as fast as possible.


Kids under 8 may only select BACK CONTROL in overtime rounds.
