The Nevada State Athletic Commission extended a temporary suspension for Jon Jones on Monday and revealed two banned substances the UFC star tested positive for in the process.
According to the NSAC's complaint, an out-of-competition sample provided by Jones on June 16 tested positive for clomiphene, which is listed as an anti-estrogenic substance on the banned list, and traces of letrozole, an aromatase inhibitor.
The Nevada district attorney's office informed the NSAC of a potential hearing date around September of October.
Jones, who was pulled from a light heavyweight championship fight against Daniel Cormier three days before UFC 200 earlier this month, is not contesting the temporary suspension.
