Rulas Arreola, also known as Raul Arreola Dosal, has travelled to Las Vegas with Canelo to prepare for a super fight with the undefeated American Terence Crawford on Saturday. It is a contest marketed as a once-in-a-lifetime event that marks the beginning of a bold new era in boxing. Arreola says he has never recommended, provided or sold any banned substance to any athlete or anybody who was subject to any anti-doping rules.
Athletic Bilbao defender Yeray Alvarez has been banned for 10 months by Uefa for failing a doping test. The 30-year-old tested positive for banned substance canrenone following a 3-0 defeat by Manchester United in the Europa League semi-finals in May. Canrenone is a diuretic that can sometimes be used as a masking agent. Spaniard Alvarez said in July that he mistakenly ingested the substance when taking a preventative medicine for hair loss which contained canrenone.
