Iain Henderson will undergo surgery today and joins Garry Ringrose on the Six Nations sidelines ahead of Ireland's Grand Slam finale with England on Saturday - but Dan Sheehan, Rónan Kelleher and Caelan Doris all remain in camp.
Ringrose suffered a head injury with eight minutes remaining of the 22-7 victory over Scotland in Murrayfield yesterday and his championship is over as he recovers.
Robbie Henshaw, who came off the bench in Edinburgh to make his comeback after four months out, is expected to start in place of Ringrose as Ireland chase a fifth successive victory in this year's championship.
