ASUNCION - Mexican teams San Luis and Guadalajara have been ordered to play their next home games in the Libertadores Cup in Colombia because of the swine flu outbreak. The South American Football Confederation (CSF) said the two sides would play their second-round home matches in Bogota. "The matches will be played on May 6, on the same day, at the Campin stadium," said CSF spokesman Nestor Benitez. The decision came after Uruguayan clubs Defensor Sporting and Nacional said they would refuse to travel should either be drawn against a Mexican team. Clubs from other countries had also expressed concern, Benitez said. The Libertadores is the region's equivalent of the European Champions League. Mexican teams are not members of the CSF but three take part in the Libertadores every year under a special agreement. The CSF said in a statement that the decision applied only to the second-round ties and a new ruling would be made should either side progress to the quarter-finals. "The measure has been taken in the face of the health conditions in Mexico...which are causing fear internationally," added the statement. The new flu strain has killed up to 176 people in Mexico. Earlier this week, the Mexican Football Federation (FMF) said that first-division games at the weekend would be played behind closed doors.
