Before even the arrest and UFC suspension, Jon Jones' year started off on a sour note.
Three days after his win over Daniel Cormier at UFC 182 in January, it came out that Jones failed a pre-fight, out-of-competition drug test for cocaine metabolites. Jones released a statement, checked himself into rehab (and out after less than a day) and the UFC fined him $25,000.
Many people still wonder why Jones wasn't suspended or fined by the Nevada Athletic Commission the way Nick Diaz was. The answer is simple: The NAC admittedly screwed up.
