Ireland captain Johnny Sexton has been ruled out for up to six weeks after suffering a twisted ankle and knee in the famous 29-20 victory over New Zealand on Saturday.
The Leinster fly-half will miss the final match of the Autumn Nations Series campaign against Argentina on Sunday and faces at least four weeks on the sidelines.
Joey Carbery came on to replace Sexton with 15 minutes to go at the Aviva Stadium and sent three penalties sailing through the posts to consign the All Blacks to defeat.
Sexton will remain with squad, while Connacht number 10 Jack Carty has been called up in the absence of the skipper.
Andy Farrell will also be able to call upon Munster back rower Gavin Coombes against the Pumas after he recovered from illness.
Ireland beat Argentina 28-17 when the two nations last met in Dublin three years ago.
