According to f4wonline.com, the title fight between Jay Heiron and Nick Diaz could be in jeopardy because Diaz failed to show up for the pre fight drug testing held by the commission:

Diaz was scheduled to take a pre-fight drug test tonight
in order to get licensed and no showed. Caesar Gracie stated Wednesday
that Diaz would appear for the test tonight in Sacramento. Neither Diaz
nor Caesar showed up for the test and representatives for Diaz said Diaz was "busy training".
Because of the time required to get test results back, CSAC believes
the test would have had to be taken tonight. Strikeforce was contacted
and promised Diaz would appear for the test Monday. CSAC has agreed to
this new date but has stated there is a good chance test results will not be back in time to license him for the show.

Nick Diaz has never been shy about smoking marijuana, and in fact he's even proud that he can get away with it:

"I can pass a drug test in eight days with herbal cleansers. I drink
10 pounds of water and sweat out 10 pounds of water every day. I'll be
fine."

Dumbass pot head

I hope it was just a mix up and gets his shit done on time.
