UFC 168 drug tests for 'Weidman vs Silva 2' event return two 'inconclusive' results

UFC 168 drug test results are in from Nevada State Athletic Commission (NSAC), which today (Nov. 22, 2013) confirmed that 20 of the 22 mixed martial arts (MMA) fighters who were tested for illegal/banned substances after competing at the "Weidman vs. Silva 2" pay-per-view (PPV) event on Dec. 28, 2013, in Las Vegas, have all passed with flying colors.

However, two fighters -- Dennis Siver and Siyar Bahadurzada -- had results that returned "inconclusive," according to FOXSports.com, which means their "B" samples will be re-examined for performance enhancing drugs such as steroids, as well as drugs of abuse like cocaine and marijuana, among others.

It's important to highlight that an "inconclusive" result, according to the report, "could signal many possibilities, ranging from the mishandling of a sample to a diluted sample. It does not necessarily indicate guilt."

The "B" sample tests for Siver -- who outworked Manny Gamburyan en route to a decision win in their Featherweight fight -- and Bahadurzada -- who dropped a decision thanks to a spirited effort from John Howard -- should be complete within two weeks.
