Thiago Silva has been banned by the Nevada athletic commision, meaning he cannot fight for 12 months. Thaigo was found to have very low levels of testosterone in his blood after his last fight at UFC 125 against Brandon Vera (which ended Brandon Vera's UFC contract ) Thiago Silva has admitted to buying a masking agent to hide the use of illegal drugs in order to change the results of his blood and urine tests. Thiago Silva claims he was using banned painkillers for an ongoing back problem - as the drug test was masked there is no way of telling wether it was indeed painkillers or PEDS being used, either way you wont see Thaigo back in the octagon until 2012
