Reaping the knee – BJJ tournament legality

U.S. Grappling rules: straight footlock legality

I originally wrote this for my old blog, but this is really pertinent info for anyone competing in a US Grappling tournament.

The legality of the “footlock,” or straight ankle lock, is perhaps the most common area of confusion in all of BJJ and submission grappling rules. Below are several examples of legal methods by which to apply the footlock vs illegal methods.

LEGAL

Note: you must fall to the same side as the leg you are attacking.

Note: my foot rests on my partner’s hip and my toes point outward.

Crossing your feet outside is OK.

Finishing belly-down is OK.

Finishing the cross-body ankle lock is OK, provided you fall to the same side as the foot you are attacking.

ILLEGAL

Note: the plane of my partner’s hip is breached. This is called “reaping the knee,” and jeopardizes the safety of his knee. This is never allowed in the gi, and is only allowed in no-gi advanced divisions.

This is illegal. You must fall to the same side of the leg you are attacking. This is never legal with the gi, and is legal for no-gi advanced only.
