For the fourth time in a row, Anderson Silva has asked to postpone his hearing with the Nevada Athletic Commission, following a couple of failed drug tests before and after his unanimous decision win with Nick Diaz at UFC 183 in January.

His new deadline will now be on August 7, as it has been confirmed by Nevada deputy attorney general, Christopher Eccles, and reported by Combate.

The reason for the new postponement has not been disclosed by Anderson Silva or his team this time, though the reason for the last ones was to wait for the results of new exams that could enhance his defense at the hearing.

Silva, of course, tested positive for performance enhancing drugs drostanolone and androstane. Later on, in February, Silva also tested positive for medicines Oxazepam and Temazepam, used to treat anxiety and sleep deprivation, respectively.

Should Silva be found guilty, his win over Nick Diaz could be overturned to a "No Contest" and he would face a suspension.
