At UFC Fight Night Macao on August 23rd, UFC contracted with an independent drug testing laboratory in Hong Kong to perform urinalysis testing on all fighters on the card. Additionally, UFC requested the laboratory to test blood samples from 4 fighters for human growth hormone (HGH), erythropoietin (EPO) and testosterone.
One of the athletes who had his blood tested was Cung Le. The laboratory results from Les blood test were sent to the UFC and showed that his blood had a total HGH level outside the reference range. Based on such results, UFC officials determined that Le had violated his promotional agreement and the UFC Fighter Conduct Policy. Consequently, UFC decided that Le should be suspended from unarmed combat competition for 12 months.
Following the announcement of Les suspension, UFC officials have been provided with medical advice regarding the elevated total HGH present in Les system. In accordance with such medical advice, UFC has determined that Les elevated total HGH by itself does not prove that he took performance-enhancing drugs before the August 23rd bout. As a result, UFC has informed Le that his suspension is rescinded.
