FIFA accepts Mexican soccer players' tainted meat excuse.

Five Mexican players who tested positive for clenbuterol before the Gold Cup in June will face no further action after FIFA determined the tests were caused by contaminated meat.

The World Anti-Doping Agency said Wednesday it had dropped its appeal at the Court of Arbitration for Sport, where it planned to challenge a Mexico Football Federation decision clearing the players of doping.

WADA says it accepted FIFA's "compelling evidence" from the recent Under-17 World Cup in Mexico that the country has a "serious health problem" with meat contaminated with clenbuterol.
