Former Ultimate Fighting Championship (UFC) Heavyweight Champion and bona fide bone-breaker Frank Mir is one of the toughest 265-pound fighters on the planet.

But even he is afraid of the Nevada State Athletic Commission (NSAC).

Mir had a chance to share his feelings with MMA Fighting on the "scary" suspension handed down to Nick Diaz earlier this week when the former Strikeforce welterweight champion appeared before the NSAC to answer for marijuana metabolites detected in his UFC 143 drug test.

Here's what he said:

"From what I understood leading into it, I thought it was an out of contest drug, to have metabolites in your system. He has a prescription for it back home, from how I understand it. Obviously, having metabolites in his system means he was not under the influence of marijuana in contest, the night they tested him, but that's why they wear suits and I wear no shirt when I go to work. I thought he was in the clear but I was wrong. [The penalty] is very scary and the fact they are who they are and I fight here in Nevada, whatever they wanna do is fine by me! Seems very fair!"

Hear more from Mir, who fights reigning champion Junior dos Santos for the heavyweight title in the main event of UFC 146 on Saturday night at the MGM Grand Garden Casino in Las Vegas, after the jump.
