Former Ultimate Fighting Championship (UFC) middleweight champion Anderson Silva continues to successfully postpone his disciplinary hearing with Nevada State Athletic Commission (NSAC), despite failing his UFC 183 drug test over four months ago.

Probably because his results are still inconclusive.

Veteran mixed martial arts (MMA) reporter and drug-testing expert Larry Pepe brings word that Silva's test results collected during the UFC 183 pay-per-view (PPV) event, which took place back on Jan. 31, 2015 in Las Vegas, Nevada, contradict one another.

The sample sent to Sports Medicine Research & Testing Laboratory (SMRTL) returned positive; however, Quest Labs reported just the opposite.

From Twitter:

Source tells me there are conflicting fight night tests. SMRTL was positive (as SMRTL test was on 1/9) but Quest Labs did test same night close in time and Anderson was negative. SMRTL B sample being tested but results are not back yet. Either way, I would assume that Silva team will use the inconsistency of the two labs' results to discredit the SMRTL positive test dated 1/9 and also point to SMRTL negative test dated 1/19 in arguing to NSAC that results are unreliable or, alternatively, that he should get reduced sentence. If you are wondering, yes, this is similar to Nick Diaz case where Quest & SMRTL were also in conflict.

SMRTL is currently testing Silva's B-sample and the results are pending.

Silva has maintained his innocence in the wake of a failed steroid test (which prompted this), but must also answer for the out-of-competition drug test that returned positive for anti-anxiety medication. In the meantime, "The Spider" is temporarily suspended from UFC until this mess can be sorted out.

Innocent until proven guilty?
