2011 Knockout of the year

[Rantcatrat]

It's not KO of the year because the combatants were female but geez was brutal:
Holly Holm was out hanging on the ropes and the Ref let it go on?!? Really, really bad by the Ref letting it go that long

The ref also missed a knockdown where Holm was visually hurt and without a doubt was dropped....he called it a slip and let her keep going
