Hindu's Horacio Agulla and SIC's Federico Serra were surprisingly included in the squad, which includes 13 backs and 17 forwards after being reduced from the 41-man preliminary squad which was named at the start of July.

Federico Aramburu and Francsico Leonelli have failed to recover from injury and will not travel to France ahead of the Group D opener against hosts France on September 7 in Paris.

Alumni's Alberto Vernet Basualdo edged out Pablo Gambarini to claim the spot as back-up hooker, while CASI's Esteban Lozada claimed the fourth and final second row berth ahead of Manuel Carriza.

Argentina have also been drawn in Group D alongside Ireland, Georgia and Namibia.
