Kanehara got his opponent pinned down on the mat with a head-and-arm choke. Things looked like they were going downhill fast but a rare reversal happened. McDonald inched his way out of a dangerous situation and applied a rear-naked-choke in return.
It was a decisive move that stunned everyone, not least his foe in the Octagon. Many are calling it a great display of Jiu-jitsu skills that other fighters can learn from.
