Association football

There have been few incidents of doping in football, mainly due to FIFA 's belief that education and prevention with constant in and out-of-competition controls play a key role in making high-profile competitions free of performance-enhancing drugs. The FIFA administration work alongside team physicians to fight for dope free competitions, having them sign a joint declaration that states they agree with having routine blood testing to check for blood doping before any FIFA World Cup.

In 2014, the biological passport was introduced in the 2014 FIFA World Cup; blood and urine samples from all players before the competition and from two players per team and per match are analysed by the Swiss Laboratory for Doping Analyses.
