Steroid profiling of players will be added to the Union of European Football Associations (UEFA) anti-doping programme next season, the European football governing body announced on Friday.
UEFA's medical committee has approved urine analysis in addition to existing blood monitoring for its biological passport programme, reports Xinhua.
In 2013, UEFA approved retrospectively analysing urine samples from 900 players to decide if steroid profiling was required. Re-testing was anonymous and positive samples would not provoke anti-doping cases.
Though top-level football has few doping cases, UEFA suspended three Russian players from CSKA Moscow in the 2009-10 season for doping violations.
