Brazilian tennis player Thomaz Bellucci has been banned for five months after failing a doping test. The 30-year-old tested positive for the diuretic and masking agent hydrochlorothiazide during the Swedish Open in July, the International Tennis Federation (ITF) said, reports Xinhua news agency. It added that Bellucci was not guilty of any "significant fault or negligence", accepting that the result was due to contaminated vitamin supplements.
