Props to the Referee

he did ok. I thought he could have used better judgement on the first knockdown and ruled that it was an illegal shot or a push or whatever, but split second it's hard to do.

I really question that this was the case. After seeing the replay I think the blow qualifies as "side of the head". When you saw it at full speed in the fight it looked very questionable though, which I think many people based their judgment off of. Perhaps someone can provide a gif.
