Sabella named Boca Juniors keeper Agustin Orion and Velez Sarsfield duo Gino Peruzzi and Fernando Gago for Friday's home game against the Cafeteros and the trip to Ecuador on June 11.
They are joining the foreign-based squad members on Monday morning in the Argentinian Football Association (AFA) training centre in Ezeiza city.
Velez boss Ricardo Gareca is angry with the AFA because he feels former Real Madrid and Roma midfielder Gago has not fully recovered from a knee injury.
"This is something the club (Velez Sarsfield) will have to solve," he said. "Gago must get over in Velez. After that, I have no objection for him to join the national team. If the player is completely recovered, I have no problems, but he has not been discharged yet."
Sabella is expected to name more players on Monday night, with Napoli defender Hugo Campagnaro and Metallist midfielder Jose Ernesto Sosa struggling to be fit.
