Four positive drug tests and two testing evasions have led to the second career drug-testing sanction of UFC heavyweight Raphael Pessoa . On Monday, the U.S. Anti-Doping Agency announced Pessoa (10-2 MMA, 1-2 UFC) has been suspended for two years as a result of four separate positive tests for hydrochlorothiazide (HCTZ) and its metabolites chlorothiazide and 4-amino-6-chloro-1,3-benzenedisulfonamide (ACB).
