According to Reuters reporter Simon Evans, CONCACAF will not dock Gold Cup points from Mexico following the revelation that players tested positive for banned substances. A decision has not yet been made on whether or not Mexico can replace the five players that they have expelled, and CONCACAF's national teams committee will meet tomorrow to determine whether or not they will be allowed to do so.
As a precautionary measure, it would be pretty surprising if Jose Manuel de la Torre's assistants were not already on the phone with the clubs of players who have been called up for Copa America, asking them if they would be willing to release the players for both tournaments. Most owners and managers would probably be understanding in this situation, but it would not be surprising if some offered up opposition. Also complicating matters is the U-20 World Cup, in which some of the Copa America squad are believed to be participating in.
