Chael Sonnen has been suspended one-year and fined $2,500 by the California State Athletic Commission after testing positive for high testosterone levels following his loss to middleweight champ Anderson Silva at UFC 117 on Aug. 7.
News of Sonnen’s failed drug test first broke on Sunday.
Sonnen can file an appeal within 30-days, but reportedly admitted to taking a banned substance while being tested.
“He only indicated that he was taking it but he never indicated why,” CSAC executive director George Dodd told SI.com. “[Sonnen] just let me know he was taking [something] and that’s when I called over an inspector to get it documented. But when you do take it you still have to show a medical reason.”
Sonnen was slated to get an immediate rematch with Silva early next year after dominating Silva before being submitted in the final round, but that title shot will now go to the winner of UFC 122′s Vitor Belfort vs. Yushin Okami.
