Group A of the 2011 CONCACAF Gold Cup was one of three groups competing of nations at CONCACAF Gold Cup 2011. The group's first round of matches were played on June, with the final round played on June 12. All six group matches were played at venues in the United States, in Dallas, Charlotte, North Carolina and Chicago. The group consisted of five-time Gold Cup champions, Mexico, as well as Costa Rica, El Salvador and Cuba.
On the eve of Mexico's second fixture against Cuba, the Mexican Football Federation removed five players from their squad due to substance abuse.[1] These players included starting goalkeeper, Guillermo Ochoa, starting center back Francisco Rodríguez and the following reserves: Sinha, Christian Bermúdez and Édgar Dueñas.[2][3] The drug they tested positive for was clenbuterol, which is used in animals to produce lean meat. The supposition for the players being injected with this substance was from eating chicken that had traceable amounts of clenbuterol in it.[4] Reports begin breaking on June 6[5] and were official on June 9. The "B" samples of those five involving players have been negative.[6]
