Midway through the second round of Joaquin Buckley vs. Impa Kasanganay during UFC Fight Night 179, Buckley delivered possibly the greatest knockout in televised mixed martial arts history.

The middleweight fighter was first blocked with one kick, but quickly flipped around with to bring a back heel kick to Kasanganay's head, knocking him unconscious immediately.


That'd be enough for me to sit a few out, and definitely make me consider calling in sick if I had a fight with Buckley coming up.
