Following a hearing on December 11, Jon Jones was granted a temporary license by the California State Athletic Commission. Jones’ recent drug testing controversy led to the UFC moving the event away from Nevada, and this very license made him eligible to compete in California on Saturday night.
According to USADA’s original statement about the controversy, Jones’ sample from December 9 tested positive for a turinabol metabolite, and they informed the Nevada Athletic Commission on the 20th. These events led to the UFC moving the event to California less than a week to the fight.
