The UFC and FOX Sports have terminated their respective broadcasting services agreements with analyst and former fighter Chael Sonnen, the companies announced in a joint release on Monday.
The decision to terminate Sonnen's broadcasting deal came days after the fighter failed a second test conducted by the Nevada Athletic Commission.
Sonnen initially tested positive in May for banned substances Anastrozole and Clomifene, both of which can be utilized to help treat men with hypogonadism, which Sonnen has said to have. Following the positive test, the fighter retired from professional MMA competition.
Sonnen was placed under suspension by the NAC for failing the initial test.
The second exam in June resulted in Sonnen having traces of performance enhancers human growth hormone (hGH) and recombinant human erythropoietin (EPO) in his system.
