The doping violation that caused Jon Jones to miss his scheduled fight against Daniel Cormier at UFC 200 was a positive test for two banned substances, the Nevada State Athletic Commission announced Monday.
According to ESPN, the substances were clomiphene, which increases testosterone secretion, and letrozole, which prevents testosterone from being synthesized into estrogen.
The NSAC has extended Jones’s temporary suspension. He also faces a possible two-year suspension.

“I would never cheat,” Jones said during a tearful press conference. “I pride myself on my work ethic.”
Jones was tested on June 16 and UFC announced on July 6 that he was being pulled from UFC 200 due to a doping violation. His fight was supposed to be a much-anticipated rematch against Cormier. A previous rematch was called off after Cormier was injured.
Cormier instead fought Anderson Silva and won by unanimous decision.
