Last weekend at ONE Fight Night 6, ONE flyweight submission grappling world champion Mikey Musumeci successfully defended his belt against sambo specialist Gantumur Bayanduuren.

It was a 10-minute dismantling of a grown man's legs. Despite Bayanduuren suffering multiple knee injuries during the bout, he never tapped out and ultimately lost via unanimous decision.

The bout had the audience and commentators grimacing at the sight of Bayanduuren's knee cap being twisted out of alignment. Mikey Musumeci's leglock technique was so tight and clean that the Mongolian grappler had no other choice but to tough out the holds. There was no way for him to escape it without tapping.

In a recent Instagram post by Musumeci, the American BJJ black belt broke down the entire leglock sequence:

"⚠️ Graphic ⚠️ - K guard entry into leg lock breaking mechanics. Here is a short clip of my entry from k guard into the mikey lock (leg lock attack using your neck :) ) from k guard it typically is the easiest entry to setup because the foot is already on your neck. I wanted to show the progression of hand positions from heel hooks. First starting on the neck, then progressing to a regular inside heel hook, then progressing to the strongest heel hook (a reverse figure 4 inside heel hook). I continued to apply breaking pressure on his leg about 8 minutes straight, but my opponent unfortunately would not tap. This resulted in us seeing how damaging these leg locks can be."

Mikey Musumeci concludes his breakdown with a very important lesson

After explaining in detail the breaking mechanics of his leglocks, Mikey Musumeci imparted the most important lesson of the entire thing: know when to tap.

"Always important to tap so you avoid surgery and a year recovery. FYI this was the most disgusting feeling ever. I literally felt every part of his knee rip like cardboard 🤮 :( @onechampionship"

In jiu-jitsu, there is no shame in tapping out when a submission is fully locked in. It's like a checkmate in chess - there's no point in making any more moves because there's nowhere to go. It's not worth risking a whole year of recovery due to surgery, not to mention the expenses that come with it.

They say that the act of tapping out or conceding a match is the ultimate dismantling of the ego. It is, perhaps, jiu-jitsu's greatest gift - a simple act that can instill humility in a fighter.
