Nate Diaz misses scheduled UFC on Fox 13 open workout

You never know what you're going to get with the Diaz brothers, and today was yet another example of that. Nate Diaz, who is scheduled to return at UFC on Fox 13 after an extended layoff, was scheduled to take part in today's open workouts ahead of the event. But guess what? He didn't show:

Diaz (17-9, 12-7 UFC) has been going through a contract dispute with the promotion, which led to his holdout. It didn't get him anywhere though. He was also recently critical of the UFC's uniform deal with Reebok, and adding this to the list makes it look like Nick's younger brother is doing everything he can to poke the UFC bear.

The TUF 5 winner is set to face off with the streaking Rafael dos Anjos in the co-main event of Saturday's card in Phoenix.
