Johnny Sexton has been passed fit for Ireland's World Cup quarter-final with Argentina after shaking off an adductor injury.
Sexton lasted just 25 minutes of Ireland's pool win over France, but has recovered in time to face the Pumas in Cardiff on Sunday.
Joe Schmidt has made three changes from the team that beat les Bleus, with Iain Henderson starting for the injured Paul O'Connell.
Peter O'Mahony was also injured in that game, and is replaced by Jordi Murphy, while Chris Henry starts at openside with Sean O'Brien out through suspension.
Donnacha Ryan and Rhys Ruddock come onto the bench, the latter only called into the squad last week to replace O'Mahony, but aside from that, it's the same team that played on Sunday.
Ireland are aiming to reach a first-ever World Cup semi-final but face an Argentina side on the up.
