He struck his vascular nerve:

The Chinese guy struck his vascular nerve.

Let me show you what vascular nerve is. This guys is your vascular nerve. What happens if in a match, a UFC fighter strikes the other fighter at his vascular nerve? And squishes it.

If the blow force is extreme enough to squish or tear the inner lining of the carotid artery, it can lead to immediate localised clotting or stroke-like symptoms. Stroke. Umar Nurmagomedov had a stroke because this son of a… struck the right side of his vascular nerve.

And then, to show he didn’t mean it, he’s striking on the other side. Look, just, just, just, just, just, there you go, there you go. He was practising that.

He struck his vascular nerve. This is like bringing a knife to a UFC fight.
