NSAC drug test hearings for Anderson Silva and Nick Diaz set for Aug. 13

Nevada State Athletic Commission (NSAC) has once again summoned Ultimate Fighting Championship (UFC) combatants Anderson Silva and Nick Diaz, who are required to appear before the governing body on Aug. 13, 2015, to answer for a pair of failed drug tests.

MMA Junkie brought word of the hearing date on Tuesday.

Both Silva and Diaz were flagged for positive drug tests in the wake of the UFC 183 pay-per-view (PPV) event, which took place all the way back in January. "The Spider" was popped for steroids -- among other things -- while Diaz flunked for marijuana.

Both parties, however, insist they did nothing wrong.

That explains the lengthy (and multiple) delays in getting this mess cleaned up. The sooner, the better, because Silva -- locked into a longterm contract -- isn't getting any younger and like Diaz, is one of the most popular fighters on the ZUFFA roster.

Any chance we see these two back inside the Octagon in 2015?

Stranger things have happened, though it should be noted that quite a bit has changed since they last saw action. Not only is every athlete bound by the promotion's Reebok sponsorship, the revamped drug testing protocols -- established in the wake of UFC 183 -- require every fighter to be tested on every card.

Sorry, Nick.
