FIFA says all samples taken from all the Super Eagles players and other national teams before and during the on-going world cup in Brazil have tested clean in its World Cup anti-doping program, though no unannounced controls have been made in Brazil.
FIFA’s chief medical officer Jiri Dvorak says analysis of all pre-competition and post-match samples was completed through the first quarterfinal match last Friday.
All 736 players have given blood samples for their individual biological passport. Two players from each team are randomly picked to give samples after each match.
Dvorak says no doping controls were taken on days between matches.
He says all samples “arrived in good condition” at the World Anti-Doping Agency-accredited laboratory in Lausanne, Switzerland, where samples are tested. WADA revoked the Rio de Janeiro lab’s credentials last year.
