What a difference a few weeks makes.
Former UFC middleweight champion Anderson Silva passed his second out-of-competition drug test, administered by Nevada State Athletic Commission (NSAC) on Jan. 19, 2015, roughly two weeks before his 185-pound showdown against Nick Diaz in the UFC 183 main event.
His blood test returned negative for performance-enhancing drugs, including human growth hormone (read the full report in PDF format here).
Silva failed his first test, conducted back on Jan. 9, for the steroids drostanolone and androsterone. The Brazilian quickly dismissed the commission's findings and accused the lab of making a "mistake" or perhaps testing a "contaminated sample."
"We're happy to get these results," NSAC Executive Director Bob Bennett told MMA Fighting.
While returning a clean second test may help "The Spider" when he faces the commission later this month -- alongside fellow test buster Nick Diaz -- it does not exonerate him from wrongdoing. That would require a clean "B sample" from the original test, which would then call into question the initial findings.
Simply put, Silva's not out of the woods just yet.
