Pumas coach Santiago Phelan on Sunday omitted three players and included Juan Martin Hernandez in his squad for the Test against Ireland on Saturday.
All three played in Argentina's 39-22 defeat by France in Lille on Saturday with only Agulla being left out because of injury.
The wing took a heavy blow to the head in a sickening clash of heads with Maxime Mermoz during the game and had to be stretchered off suffering from concussion.
However, Phelan felt confident enough to restore star back Juan Martin Hernandez, the veteran utility back having recovered sufficiently from a knock he took in the 26-12 win over Six Nations Grand Slam champions Wales the previous week.
Phelan also recalled Santiago Fernandez and Maximiliano Bustos, who both play their club rugby in France for Montpellier.
Argentina travelled to Dublin on Sunday and will have their first training session on Monday ahead of their 18th meeting with the Irish.
Marcos Ayerza, Marcelo Bosch, Maximiliano Bustos, Gonzalo Camacho, Manuel Carizza, Santiago Cordero, Agustn Creevy, Tomas Cubelli, Tomas De la Vega, Julio Farias Cabello, Juan Martn Fernandez Lobbe (capt), Santiago Fernandez, Francisco Gomez Kodela, Juan Cruz Guillemain, Eusebio Guinazu, Juan Martin Hernandez, Juan Jose Imhoff, Martn Landajo, Juan Manuel Leguizamon, Tomas Leonardi, Nahuel Lobo, Manuel Montero, Bruno Postiglioni, Federico Sanchez, Leonardo Senatore, Gonzalo Tiesu, Joaquin Tuculet, Toms Vallejos, Nicolas Vergallo.
