I think I missed that when I was fast forwarding through the live feed replay the first time. I didn't catch the headbutt to the chin either though. Sometimes the wrestlers just slip and I was focused on seeing exactly how his feet slipped so I missed Churanoumi's chin hitting Kotoshoho.

Back a little over 10 years ago the Egyptian wrestler Oosunaarashi delivered a forearm blow off the lines that knocked out his opponent briefly and he crumpled a bit like Kotoshoho did here.
