Jon Jones Pleads Not Guilty To Charges ... In Drug Test Incident Case
UFC heavyweight champion Jon Jones isn't tapping out in his ongoing legal battle ... entering a not-guilty plea for the two misdemeanor charges he's facing in relation to a drug test gone wrong earlier this year.
Jones -- who appeared in New Mexico court virtually -- was charged with assault and interference with communications earlier this week ... after a testing agent claimed he made threats and took their cell phone when they popped up at his Albuquerque home unannounced back in March.
As we previously reported, two drug testing agents for the UFC's anti-doping partners -- Drug Free Sport International -- went to Jones' pad to collect a pee sample ... but in a police report, one of the agents told authorities Jon grew agitated with her after he was unable to provide a urine sample.
