Report: Photo shows negative ‘B’ sample for Silva at UFC 183
Silva has postponed his hearing with the NSAC for some reason, but it could be because the second ‘B’ sample showed a negative result, contradicting the first sample.

Following UFC 183 it was revealed that Anderson Silva tested positive for a banned substance. Silva has multiple times postponed his hearing with the Nevada commission for some reason, but it could be because the second ‘b’ sample showed a negative result, contradicting the first sample:
According to Jorge Correa of the Brazilian blog Na Grade do MMA, the former Middleweight champion submitted two urine samples on Jan. 31, 2015, two minutes apart. The first sample was submitted to Quest Diagnostics and the second to Sports Medicine Research & Testing Laboratory. The second test came back positive and was sent to the Nevada State Athletic Commission (NSAC).
