Joe Schmidt has been forced into three changes for Ireland's Rugby World Cup quarter-final with Argentina, but Jonathan Sexton is included.
Jonathan Sexton has been named in an Ireland team that includes three enforced changes for Sunday's Rugby World Cup quarter-final against Argentina.
Influential fly-half Sexton was a doubt for the last-eight clash with the Pumas at the Millennium Stadium after coming off in the first half of the Pool D decider against France last weekend with a groin injury.
But Sexton has been passed fit to start in Cardiff, so Ian Madigan has to settle for a place on the bench once again after impressing as a replacement against Les Bleus.
Iain Henderson comes in at lock in place of captain Paul O'Connell, whose international career came to an end when he limped off with a hamstring injury in the victory over France.
Chris Henry gets his chance due to Sean O'Brien's suspension, while Jordi Murphy also starts after Peter O'Mahony was injured in a brutal encounter with Philippe Saint-Andre's men.
Rhys Ruddock could make his World Cup debut from the bench after being drafted into the squad this week.
Ireland team: Rob Kearney, Jonathan Sexton, Dave Kearney, Robbie Henshaw, Keith Earls, Tommy Bowe, Conor Murray, Cian Healy, Rory Best, Mike Ross, Devin Toner, Iain Henderson, Jordi Murphy, Chris Henry, Jamie Heaslip.
Replacements: Richardt Strauss, Jack McGrath, Nathan White, Donnacha Ryan, Rhys Ruddock, Eoin Reddan, Ian Madigan, Luke Fitzgerald.
