Sean Sherk once said this about fighting in California,

"There's no reason for me to ever fight in California again. The way they treated my case and the way they handled everything was so unprofessional that there's absolutely no way I'll ever fight in the state of California again, unless they get rid of the entire commission and hire a whole new commission."

That statement was due to Sherk's positive steroid test at UFC 73. Sherk appealed the positive test and lost. In defense of Sherk the CSAC handled the appeal very poorly delaying his hearing and not having the correct information on hand.

Sherk was scheduled to fight Gleison Tibau at UFC 104 in Los Angeles, California. That scheduled fight raised a few eyebrows since Sherk said he would never fight there. Don't worry, Sherk suffered an injury and withdrew from his fight. Or did he?

According to Dave Meltzer of the Wrestling Observer,

Word of the injury got out on the evening of 9/2, a few hours after he was scheduled to take a random drug test by the California State Athletic Commission. He didn't get on the flight to California and when he no-showed, UFC informed the commission that Sherk was injured and was off the card"

It doesn't take a conspiracy theorist to connect the dots.

Bloodyelbow contacted Monte Cox and he says this is the equivalent of talking about the second shooter in the grassy knoll.

Sean has passed 7 drug tests since the California incident... he separated his shoulder in training and had to pull out of his fight... MRI was sent to Zuffa.  He didn't skip any test... if you're not fighting, you're not going to apply for a license. No big conspiracy in this.
