The arrest comes just months before Diaz is scheduled to step into the octagon for one of the biggest fights of his career, a Jan. 31, 2015 match-up against former UFC middleweight champion Anderson Silva during UFC 183. Diaz has not fought since March 2013, when he lost the UFC welterweight title fight to Georges St-Pierre.
Diaz was pulled over during a routine traffic stop, during which the officer came to believe Diaz was under the influence of alcohol. Lodi, Calif., police officials reported that Diaz was polite during his arrest. The only problem, officers said, arose when Diaz attempted to force himself to vomit after being told not to do so. Police believed he was trying to rid his body of alcohol, and subsequently charged him with destruction of evidence and obstruction.
According to the Lodi News-Sentinel, Diaz was also charged with driving on a suspended license. He was released the following morning.
The UFC has yet to take action, saying in a statement:
"We are aware of the situation and are in the process of gathering the facts...We understand that there is a legal process that will now take place and that Nick Diaz will have the opportunity to address the situation in the near future."
Diaz, who is 26-9-1 in his career, has encountered trouble with marijuana before, testing positive after two previous fights.
