LAS VEGAS - The UFC has fined light-heavyweight champion Jon (Bones) Jones US$25,000 for violating its Athlete Code of Conduct policy.

Jones tested positive for cocaine during an out-of-competition drug test conducted by the Nevada Athletic Commission on Dec. 4, 2014.

Jones fought a month later, defeating Daniel Cormier at UFC 182. His basic purse for the win was listed at $500,000.

He was allowed to compete because cocaine is only banned by the World Anti-Doping Association in competition. The Nevada commission follows WADA's lead.
