With World Cup qualification secured, the Mexican national team does not require the services of the entire squad.
As such, manager Javier Aguirre released Rafael Marquez and Guillermo Franco back to their respective clubs.
Marquez's absence is due to more than just the team's qualification, however, as Marquez picked up a yellow card and was not going to be able to play in Mexico's final game, a match at Trinidad & Tobago.
Franco, meanwhile, is headed back to England to rejoin West Ham United.
Other players, such as Cuauhtemoc Blanco, remained with the team and practiced on Monday, the final training session ahead of the team's trip to Port-of-Spain. Blanco was not expected to play against El Salvador but made a surprise start and scored goal in the decisive match, a 4-1 win over La Selecta.
Unless another player is lost, Mexico will face Trinidad with a 19-man roster.
