Contepomi set to face Scotland
Argentina captain Felipe Contepomi is set to return from injury for the must-win World Cup Pool B clash with Scotland in Wellington on Sunday.
Also returning from injury is back row Julio Farias Cabello, with Alejandro Campos left out of the matchday 22 altogether and Lucas Gonzalez Ambrosino dropping to the replacements' bench.
Contepomi's inclusion means Martin Rodriguez has been moved to full-back.
Contepomi suffered a rib injury in the opening 13-9 loss to England and missed last week's 43-8 defeat of Romania.
He said: "The idea is to play. Today I had full-on training - it was the day when I was going to try myself, full contact and everything.
"It was okay. It's not pain free, but I think it worked well.
"Hopefully I will be playing if nothing happens in the next 48 hours.
"Anything can happen in a game, but my idea is to try to play 80 minutes."
Argentina team: M Rodriguez, G Camacho, M Bosch, F Contepomi (capt), H Agulla, S Fernandez, N Vergallo; R Roncero, M Ledesma, J Figallo, M Carizza, P Albacete, J Farias Cabello, JM Leguizamon, JM Fernandez Lobbe.
Replacements: A Creevy, M Scelzo, M Galarza, G Fessia, A Lalanne, L Gonzalez Amorosino, J Imhoff.
