He Was Already Knocked Out, And Then He Fought Back

That is not possible.

When it comes to toughness, it's hard to beat Cheick Kongo.

The French UFC fighter may have eight losses on his record, but he's proven time and time again that he is nearly impossible to bring down. In the 2011 video above, Kongo is seen weathering a barrage of punches that look like they actually knock him out.

Somehow, though, the ref doesn't stop the fight. Kongo gets a second wind and fights back, delivering a blow right on the button that leaves opponent Pat Barry motionless on the mat. 

Check it out for yourself. We're sure you'll be just as amazed as the announcers.
