Fox Sports and UFC issued the following statement:
UFC AND FOX SPORTS TERMINATE BROADCASTING SERVICES AGREEMENTS WITH CHAEL SONNEN
Las Vegas, Nev. – 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.
Sonnen tested positive for banned substances and announced his retirment shortly thereafter on UFC Tonight. On Saturday, reports came out about a second drug test that he failed.
