NSAC: Thiago Silva’s Sample ‘Inconsistent with Human Urine’

By Mike Whitman Mar 29, 2011
The Nevada State Athletic Commission on Tuesday filed a complaint regarding UFC light heavyweight Thiago Silva’s drug screen from UFC 125, alleging that Silva’s provided urine sample was “inconsistent with human urine.”

The commission further alleges in the complaint that the American Top Team product submitted an “adulterated and/or substituted specimen for testing in the urinalysis.”

Silva recorded a lopsided unanimous decision win over Brandon Vera at the Jan. 1 event, which took place at the MGM Grand Garden Arena in Las Vegas.

Following the event, according to the NSAC, Silva’s “A” sample was flagged as containing a banned substance. The commission then tested Silva's “B” sample and found the results to be inconclusive. Upon further scrutiny, the NSAC found that Silva’s test was allegedly tampered with, and the commission submitted the sample to Salt Lake City’s Sports Medicine Research and Testing Laboratory, which found the same result.

NSAC director Keith Kizer informed Sherdog.com on Tuesday that Silva has not been suspended, as the fighter has 20 days to file an answer to the commission’s complaint. However, a preliminary hearing will be held on April 7 to discuss a temporary suspension. ESPN.com writer Josh Gross reported on Twitter that Kizer will ask the commission to overturn Silva’s win.

Silva’s fight with Vera marked the Brazilian’s first bout since his January 2010 loss to Rashad Evans.
