Ireland beat France to avoid a quarter-final encounter with New Zealand, but suffered injuries to Johnny Sexton, Paul O'Connell and Peter O'Mahony.
Sexton suffered a suspected groin injury, before O'Connell was carried off at the end of the first half.
Leading 9-6 at half-time, Rob Kearney's try increased Ireland's lead before O'Mahony had to be taken off.
Conor Murray added a further late try as the gutsy Irish set up a quarter-final with Argentina next Sunday.
