UFC light heavyweight champion Jon Jones has been suspended for one year by the United States Anti-Doping Agency (USADA).
USADA announced on Monday that Jones will "receive the maximum one-year period of ineligibility for his anti-doping policy violation".
The suspension begins retroactively from July 6, when he was pulled from a UFC 200 fight against Daniel Cormier.
Jones received a provisional suspension in July after testing positive for banned substances clomiphene and letrozole.
The 29-year-old claimed he had ingested a tainted sexual performance pill.
USADA confirmed the pill he took was contaminated but ruled Jones did not do his duty of diligence in making sure the substance was permitted by the UFC's anti-doping policy and the World Anti-Doping Agency's code.
Jones can still be punished by the Nevada State Athletic Commission, though no hearing has being scheduled.
