There are two vacancies left for the hooker positions in the starting side and also on the bench, as both Jerry Flannery and Rory Best are recovering from injuries they picked up in recent matches.

The final two spots will be named later in the week as soon as medical clearance for the players is confirmed.

Ireland captain Brian O'Driscoll said: "It's important that Irish supporters realise that our poor results are not down to a lack of effort. We had a meeting on Monday and spoke about how important it was for us and everyone who supports Irish rugby that we can't simply bow our heads because things haven't gone right to date. We still have an opportunity to qualify for the play-offs and that's got to be our sole focus."
