Anderson Silva's fighting career—at least as we know it—may already be over.
Details of Silva's second failed drug test emerged this week, casting his future into peril. The former UFC middleweight champion faces a possible four-year ban after turning up positive for synthetic testosterone and a banned diuretic in a sample collected in October 2017.
His reps are apparently asking for a lighter sentence, arguing that Silva's first test failures—for a pair of steroids in January 2015—didn't fall under the auspices of the UFC's current anti-doping policy and therefore shouldn't count against him, according to Combate (h/t MMA Fighting's Marc Raimondi).
