Ireland number eight Jamie Heaslip has been named in their squad for the final two matches of the Six Nations as he recovers from injury.
Heaslip missed the Round 3 game against England with a back injury caused by Pascal Papé of France.
Veteran centre Gordon D'Arcy has been left out of the 36-man squad entirely in a move that will no doubt raise speculation regarding his international future.
Props Michael Bent and Tadhg Furlong, along with second row Dan Tuohy, have all been added to the group.
