In one of the most brutal KOs you will see on MMA, Uriah Hall knocked out Adam Cella in a fight shown during this third episode of The Ultimate Fighter 17 on FX. To put how bad the KO was in context, this is what UFC president Dana White tweeted about the incident:

“In my 13 years at UFC I have only seen 5 KO’s like this,” read the first update, followed by: “He was out for 4 mins! Got on the stool at 6 in the ambulance at 9!”

It was a spinning back kick that did the damage (thankfully, Cella reportedly did not suffer serious injury and will be able to continue in the series), and Hall described the moment as follows.

“That’s my favorite technique,” he said, according to mixedmartialarts.com. “It’s a little bit of an unorthodox move. If you have good speed and good whip, you can catch someone, and it’s really deadly. I love to use that technique, and just from being in the ring with him, I’d seen how he would drop his hand a little bit. I had the chance and I capitalized on it and I took it.”
