The California State Athletic Commission has been dealing with a lot of controversy lately due to finance issues. While it's not overly surprising to see this bleed into their ability to cover fights in the state adequately, this piece of news is still kind of bizarre - the drug tests for the Strikeforce: Rousey vs. Kaufman card came back as "invalid". And the commission says they don't have any more information on the matter (via MMA Fighting):

The commission would not comment any further, with a spokesperson saying, "we have no additional information" when asked for further details. An "invalid" test is one in which a laboratory is prevented from obtaining a valid result due to any number of circumstances surrounding it.

Marc Ratner, the UFC vice president of regulatory affairs, gave a pseudo-explanation:

"It was something wrong with the collection method," he said. "Our fighters in good conscience gave their specimens. That's all I know."

Asked if he'd ever experienced such an issue in the past, Ratner said no.

"In all my years in the Nevada commission, we had some test that was out of range with the temperature or something, but that was one out of thousands, so it's very, very rare," he said.

Considering that Strikeforce is about to run another event in California (Sacramento, to be exact) in a little over a month, this might be something they want to figure out soon. If they can't even handle drug testing correctly, what else are they messing up?

UPDATE: An email from CSAC interim director Kathi Burns says the following:

"The results of the drug testing for the August 18, 2012 Strikeforce event will be provided later this week or early next week. I spoke with the lab just a few moments ago and found that a delay in processing the results has occurred due to a simple, but correctable clerical error."
