SAO PAULO — Brazil midfielder Fred tested positive for the banned substance hydrochlorothiazide during the June-July Copa America, the Brazilian Football Confederation (CBF) said Friday. The 22-year-old Shakhtar Donetsk player denied using the substance, which is a diuretic. “I have never used any illicit substance,” he said in a statement. “I trust in my innocence and I am going to prove it to the proper authorities. I have a clean career and I have everyone's support.” — Reuters
