According to MMAJunkie, multiple sources close to the situation have confirmed to them that Anderson Silva failed a second drug test.
“The date of Silva’s second failed test is not yet known, and an open-records request made by MMAjunkie has not yet been answered by the state of Nevada.”
Although the date of this test isn’t known at this time, MMAJunkie’s John Morgan confirmed via their twitter that this failed test is not the B-sample of Anderson’s original 9th January failed test
@johnjoeoregan @MMAjunkie Separate test. As of yesterday, Silva camp hadn’t even asked for B sample to be tested, according to NSAC.
