Andy Farrell is expected to reshuffle his options this weekend.
Jack Conan has been called up to the Ireland squad for Sunday's Six Nations game against France at Lansdowne Road.
Peter O'Mahony will find out later what punishment he'll face for his red card in Ireland's Six Nations opener against Wales on Sunday.
A disciplinary hearing will take place this afternoon by video conference but O'Mahony is set to be unavailable for Sunday's match.
