"Former UFC light heavyweight champion Jon Jones was initially facing a 48-month suspension due to his positive test for turinabol, but that was reduced to just 18 months following arbitration. Three months of that reduction were due to a small reduction in Jones’ degree of fault, and
the arbitrator believing he did not deliberately intend to cheat, but thirty months were due to the “snitching” clause in the UFC’s anti-doping program."
"What this means is that Jones has been providing USADA with information that will lead to either USADA sanctioning individuals, or criminal investigations into individuals."
