YouTuber Olajide Olayinka Williams Olatunji, aka KSI, was brave enough to take on a grappling challenge against Demetrious Johnson.

Johnson revealed that KSI made a bet to try and see if he could survive one minute on the ground with the former UFC flyweight champ without getting submitted. “Mighty Mouse” acknowledged that the YouTuber-turned-boxer didn’t have much grappling experience.
