Johnny Hendricks stunned Joe Rogan with 46-second KO
At the start of round one, Hendricks leapt in with a left-hand shot that landed perfectly.
Kampmann smacked his head off the floor as he was knocked unconscious after just 46 seconds.
As Hendricks celebrated and doctors attended to his victim, Joe Rogan voiced his shock at the KO.
The UFC commentator suggested ‘Bigg Rigg’ was the biggest puncher in MMA after watching him beat Kampmann in a way nobody else had been able to.
“Oh, man! There is no question about this guy’s power, man,” Rogan said on the UFC 154 broadcast.
“Are you kidding me? Are you kidding me? This dude has unbelievable power. Wow!
“Nobody has done that to Kampmann before. Let me tell you something, Paul Daley is one of the biggest power strikers in MMA, and he didn’t do that to Kampmann.
“Look at this shot. Look at the amount of distance he covers with this. Boom! And he did it by setting it up with the right. Boom!
“Man, that guy hits hard! You know, he might be the biggest power puncher in MMA.
“If that guy hits anybody, they go night-night.”
