Argentina have added centre Marcelo Bosch and full-back Lucas Gonzalez Amorosino to their squad ahead of the coming week's fixture against France.
Bosch and Amorosino offer head coach Santiago Phelan fresh options for a back-line that is now missing Felipe Contepomi. The veteran was carried off during their victory over Wales with an injury that could spell the end of his Test career.
Also missing from the squad due to injury is prop Juan Gomez so coach Phelan has added Biarritz front-rower Francisco Gomez Kodela and Stade Francais lock Nahuel Lobo for extra depth.
Argentina squad: Marcos Ayerza, Manuel Carizza, Agustin Creevy, Tomas De la Vega, Julio Farias Cabello, Juan Martin Fernandez Lobbe (captain), Juan Figallo, Francisco Gomez Kodela, Eusebio Guinazu, Juan Cruz Guillemain, Juan Manuel Leguizamon, Tomas Leonardi, Nahuel Lobo, Bruno Postiglioni, Leonardo Senatore, Tomas Vallejos, Horacio Agulla, Marcelo Bosch, Gonzalo Camacho, Lucas Gonzalez Amorosino, Santiago Cordero, Tomas Cubelli, Juan Martin Hernandez, Juan Josť Imhoff, Martin Landajo, Manuel Montero, Nicolas Sanchez, Gonzalo Tiesi, Joaquin Tuculet, Nicolas Vergallo.
