a World Cup qualifier against Argentina after ingesting a tea containing the substance. Guerrero was initially suspended for twelve months, but this was later halved by FIFA's appeal committee. WADA, in turn, appealed to CAS, and they imposed the fourteen-month ban in May 2018, which will cause Guerrero to miss the 2018 FIFA World Cup.
