Watch Demetrious Johnson shock KSI in seconds during 1 minute grappling challenge

KSI knew he was outgunned grappling former UFC flyweight champ Demetrious Johnson, but he didn’t expect things to go the way it did.

The Misfits Boxing fighter and promoter joined Johnson for an MMA and grappling lesson on Johnson’s YouTube channel. KSI and “Mighty Mouse” agreed to a one-minute grappling challenge where KSI would begin in full mount and have to survive for 60 seconds.

Unfortunately for KSI, he didn’t even make it 20 seconds, as you can see in the video below.
