Ireland have named their team to play France in the Six Nations but have left the flyhalf position open due to injuries.
There are three confirmed changes from the last outing, with Mike McCarthy and Cian Healy coming into the forwards in place of Donncha O'Callaghan and Tom Court respectively.
Craig Gilroy has failed to recover sufficiently from his groin strain and has been ruled out of the game with Fergus McFadden coming into the team on the right wing in his place.
An opening has been left in the match 23 for the starting and replacement out half positions as Paddy Jackson has a tight hamstring which was being carefully monitored during training this morning.
Jonathan Sexton has also continued his rehabilitation programme on his hamstring injury and a decision on both positions will be made later this week.
Declan Fitzpatrick has also been ruled out of the game due to a calf strain and his position among the replacements will be confirmed later in the week.
