Ireland scrum coach Greg Feek has admitted his side are willing to risk Johnny Sexton for Monday's quarter-final against Argentina even if the Leinster No. 10 is not fully fit.
Sexton limped off in the 25th minute of his side's 24-9 victory against France with a groin injury and was replaced by Ian Madigan.
Ireland, however, will do all they can to get Sexton fit and firing. 'Johnny did about three and a half kilometres of running today so that's a positive,' former All Black Feek said yesterday.
'We're quietly confident and we'll see how he goes. But here it's do-or-die type stuff, so there might be some allowances around a few things -especially with our medical staff and strength and conditioners, they've got a good feel on things.'
Ireland's back-row resources have also been hit by injuries and suspension for Monday's meeting with Argentina, but Jordi Murphy is hoping to fill the void if called upon.
Munster flanker Peter O'Mahony was ruled out with a knee ligament injury earlier this week while star openside Sean O'Brien will sit out the match after receiving a one-week ban for striking France lock Pascal Pape.
