While the Jon Jones-Daniel Cormier bout got all the hype at UFC 182 last night, the best knockout of the evening went to lightweight Paul Felder, whose ridiculous spinning back-fist knocked opponent Danny Castillo out cold and is a very early contender for Knockout of the Year. UFC officials agreed, and handed the undefeated Felder (10-0) a $50,000 check after the event for “Performance of the Night.”

It's tough not to love the sneaky nonchalance of the KO. So casual, but so painful.
