It seemed like there was finally a firm date for Nick Diaz to face the NAC, but his hearing has been delayed yet again.
Nick Diaz and Anderson Silva competed at UFC 183 in January. That was so long ago in terms of MMA cards that I can barely remember it. Most do remember the sideshow after the event though - Diaz and Silva both tested positive for banned substances around the fight. Nick's was for marijuana metabolites, his alleged third offense.
There have been a lot of questions about the testing done on his samples by separate labs though, so a NAC hearing to determine guilt or innocence would seem to be the best thing for everyone involved.
