Tuivasa: Lewis is the king of knockouts, but I'm going to shock the world

Lewis is the king of knockouts. His resume is on fire for itself. I have been a fan of Derrick and have watched him fight since the beginning of my mixed martial arts career, so I know what he is capable of. But he also knows what I can do in a cage, so that's the point of our fight.

I'm younger than him and faster, and I'm going to shock the world," Tuiswasa said on The MMA Hour.
