VIDEO: Anthony Joshua Knocked Down Twice in 3rd Round by Huge Underdog Andy Ruiz

OH, MY! What is happening here at Madison Square Garden? After showing his class and sending Andy Ruiz Jr. to the canvas, unified world heavyweight champ Anthony Joshua was just humbled in profound fashion. After taking a big lick and falling down backwards, the British bruiser was felled a second time at the end of the third round, finding himself saved by the bell.

That was a stunner. But the next one was freaking bonkers.

Are you kidding me? We're talking about an undefeated world champ faltering in his first-ever fight outside his native Britain.

And it all paled in comparison to what happened next.
