Chicago:Francisco "Kikin" Fonseca, Pavel Pardo, Ricardo Osorio and Carlos Salcido were dropped from Mexico's roster for the Copa America, joining its rival the United States in taking a reduced team to the South American nations championship.
Salcido said he was just too physically and mentally exhausted to play in Venezuela.
"I'm not at 100 per cent. I'm not enjoying myself on the field, and in order not to affect things and affect my teammates, I prefer to step aside," Salcido said on Friday in Chicago, where the Mexican squad is preparing for Sunday's final against the United States in the CONCACAF Gold Cup.
On Thursday, Pardo and Osorio said they wouldn't play in the Copa America, chosing to return to their families before rejoining Stuttgart, where they play in the German Bundesliga.
Manager Hugo Sanchez also left Fonseca, a forward for Mexico's Tigres, off the roster.
"It hurts not to be in the America Cup, not to be with my teammates but that is part of soccer and part of life," Fonseca said Friday.
"Obviously if I'm not there, it's because he (Sanchez) doesn't have the same confidence in me he had at one point," he added.
Sanchez, however, will not be without any of his regulars. His roster announced Friday includes goalkeeper Oswaldo Sanchez, defender Rafael Marquez and strikers Cuauhtemoc Blanco, Jared Borgetti and Omar Bravo.
The tournament opens on Tuesday. The Americans also announced their roster Friday, announcing they will take a roster including 16 players with 10 caps or fewer.
