FIFA have branded the World Cup 'drug free' after the
organisation's medical committee reported that there have been no
positive doping tests during or in the build-up to the tournament.
More than 1,000 tests have been conducted - 777 out of competition
and 232 during the tournament - and none have come back with a positive
result.
“We have not found any prohibitive [sic]substances... either prior to or during competition,” FIFA's chief medical officer Jiri Dvorak told a press conference.
The four teams remaining in the competition will continue to be tested until the conclusion of the event.
All tests have taken place at the World Anti-Doping Agency’s laboratory in Switzerland after the agency revoked the license of the drug-testing facility in Rio de Janeiro for failing to meet the necessary standards.
