Diaz was given one of the most sensationally bad penalties in the history of sports jurisprudence in September when Nevada suspended him for five years and fined him $165,000 for a drug violation it couldn't come close to proving. Nevada alleged that Diaz failed a marijuana test administered to him after his bout with Anderson Silva at UFC 183 in January. Though it failed to prove it – there were two tests that appeared to exonerate Diaz that Nevada chose to ignore – it penalized him anyway.
