Chael Sonnen may have retired from pro fighting after failing a random drug test recently, but the results of a second failed drug test has cost him his commentating duties.

According to a statement released by the UFC and FOX Sports on Monday, Sonnen will no longer be part of the promotion’s broadcasts.

The UFC and FOX Sports organizations announced today the termination of their respective broadcasting services agreements with analyst Chael Sonnen. This decision comes in light of Sonnen failing a second test conducted by the Nevada Athletic Commission for banned substances in June. Sonnen was previously under temporary suspension by the Nevada Athletic Commission for failing an initial test conducted in May.

In the first random test Sonnen was required to take by the Nevada State Athletic Commission, the 37 year-old tested positive for anastrozole and clomiphene. Sonnen argued that he was taking the substances as a means to help his transition off testosterone-replacement-therapy.

A second test Sonnen took, however, also reportedly revealed the presence of the banned substances human growth hormone (HGH) and recombinant human erythropoietin (EPO).

Sonnen, who has been temporarily suspended by the NSAC, has another hearing with the organization on July 23rd. The accomplished wrestler was originally scheduled to fight Wanderlei Silva at UFC 175 this Saturday.

The former middleweight contender was a regular presence on FOX Sports broadcasts related to the UFC, including the channel’s “UFC Tonight.”
