Uncapped duo James Lowe and Billy Burns, as well as experienced wing Keith Earls, have been added to Andy Farrell's Ireland squad for the Autumn Nations Cup.
New Zealand-born Leinster wing Lowe has been training with Ireland since the squad originally got together in October for the rescheduled Six Nations Tests, but only became eligible to appear for the side under residency this month.
Ulster out-half Billy Burns has replaced Connacht No 10 Jack Carty within the 34-man squad, while No 8 Jack Conan has returned to Leinster to continue his rehab programme.
A third uncapped player within the panel is Munster back-three Shane Daly, who is yet to make his debut despite having been with the squad over the last month.
Connacht pair Kieran Marmion and Quinn Roux have been released to play for their province this weekend against Dragons in the PRO14, and will re-join the national set-up thereafter.
Ulster second row Iain Henderson will be available for selection again following his suspension, but players such as tighthead Tadhg Furlong, loosehead Dave Kilcoyne, hooker Niall Scannell, centre Garry Ringrose and wing Jordan Larmour remain out injured.
Ulster scrum-half John Cooney has once again been overlooked within the squad selection, as has Leinster nine Luke McGrath.
Ireland begin their Autumn Nations Cup campaign by hosting Wales in Dublin next Friday (November 13), before travelling to play England at Twickenham (November 21), hosting Georgia (November 28) and then playing one more play-off Test in Dublin against one of France, Scotland, Fiji or Italy (December 5).
