Special rules

Situations with their own rule beyond the table.

Knee reaping (19)

  • Knee reaping is when one athlete places the thigh behind the opponent’s leg and passes their own calf across the front of the opponent’s body, above the knee, placing their foot beyond the opponent’s vertical midline and applying pressure on the knee from the outside in, while keeping the foot of the leg at risk trapped between their hip and armpit.
  • The foot counts as trapped even when it is not held — the athlete’s body can block it; when one athlete is standing, the foot of the endangered knee stepping on the ground counts as trapped.
  • It is a very serious foul when the reaping athlete’s foot passes the vertical limit (outer edge) of the opponent’s body, or when the reaping happens with a submission locked in.
  • Very serious foul: when the athlete spins inward in the 50/50 guard and, at the start of the spin, the opponent is standing on the ground with the foot that is in the guard (trapped foot).
  • It is a serious foul when the athlete performs the movement with the foot passing the opponent’s vertical midline: the referee stops the match, repositions the athletes and applies the penalty.
  • Up to purple belt: when both athletes are seated with legs crossed in a legal position and one stands up, making the other’s position illegal, the referee stops the match, places athlete B seated and athlete A standing at a distance that allows new grips, and restarts. If this happens after a sweep, the referee waits 3 seconds for stabilization, stops the match, awards 2 points to athlete A, who is on top, and restarts the same way.
  • At brown and black belt, there is no stoppage or penalty in that case.

Jumping to guard — serious foul (6.2.2 W)

In age divisions up to 15 years old (all belts) and at all ages for white belt, it is a serious foul to jump to pull a standing opponent into closed guard, including any and every attack that starts by jumping to guard, such as the Flying Triangle and the Flying Armlock. The referee will restart the match with both athletes standing. If the athlete jumps to guard while defending a takedown or sweep, the penalty comes with 2 points to the opponent.
