Pretty sure Zuffa is/was sending a msg. He's got a decent record. Look at his stable mate; Hardy. For some reason he was still in after losing four in a row.
It's too bad cuz he is an exciting fighter to watch. Unfortunately he did this to himself with the help of Koscheck goading him. Imagine if he won...he would have been a UFC title contender ultimately losing, but still collecting bonuses. One crucial error in judgement cost him his career...at least for the time being.

Baked, not fried... the healthy choice.
