Ireland hooker Jerry Flannery is back in the squad for the next game for the Irish. Flannery has been out of action since October with a calf injury.
Flanker Alan Quinlan (dislocated elbow) will be out for up to two months and prop Dave Ryan (shoulder) faces several weeks on the sidelines.
Teenage winger Craig Gilroy has been left out of the Ulster squad while Irish hooker Rory Best is back after a broken cheekbone.
Gilroy is an absentee for the interprovincial showdown after scoring five tries in his first three Ulster appearances.
The Irish Rugby Football Union has announced that their latest ticket pricing plans for next years match against France and England. The Aviva Stadium failed to sell out at any time during the four recent autumn Tests with the 46,302 attendance for New Zealand the best by some margin.
The pricing strategy was condemned and have responded by introducing five categories for 30,000 seats.
These range in cost from just over £12 to slightly over £105.
Pat Fitzgerald, Chairman of the IRFU Commercial and Marketing Committee, who chaired the ticket working group, said the move would “go a long way towards balancing the requirements of the differing constituents”.
Ireland are set to make five changes for the match against Argentina. ull-back Geordan Murphy and winger Andrew Trimble come in for the injured Rob Kearney and Luke Fitzgerald while Peter Stringer starts at scrum-half.
In the front row, Sean Cronin replaces sidelined Rory Best and Tony Buckley’s return from a hip injury means Tom Court reverts to the replacements.
Argentina have made three changes from the team beaten last weekend by France.
Wing Horacio Agulla replaces Gonzalo Camacho while centre Marcelo Bosch takes over from Santiago Fernandez.
The only change in the forwards is the inclusion of flanker Julio Farias Cabello in place of Miguel de Achaval.
