Óscar Zambrano

Óscar Zambrano is an Ecuadorian professional footballer who plays as a midfielder. He recently made headlines due to a doping scandal, as he tested positive for clortalidone, a banned diuretic, following the Recopa Sudamericana 2024 final. He has been handed a 16-month suspension by the Confederación Sudamericana de Fútbol (Conmebol). Zambrano's defense claims that his positive test resulted from an allergic reaction due to contaminated food, specifically ceviche with shrimp juice, which led to emergency medical treatment involving the prohibited substance. His case is now set to be evaluated by the Court of Arbitration for Sport (TAS) on March 13.
