The team is currently playing in the World Championships in Georgia
Five of Ireland's U20 rugby squad have suffered injuries which will prevent them from playing any further part in the World Championships in Georgia.
Marcus Rea (shoulder), Jack Kelly (ankle), Sean Masterson (ankle), Conor Fitzgerald (ankle) and Liam Coombes (thigh) are all returning to Ireland following a medical review.
All five players featured in Ireland's 69-3 defeat to New Zealand on Thursday.
Mark Keane (Instonians/Ulster), Cormac Daly (Navan/Leinster) and Luke Carty (Buccaneers/Connacht) have been drafted in to link up with the squad as Ireland prepare to face Samoa on Tuesday.
After losing all of their pool games, Ireland are now vying for a ninth-place finish in the play-offs.
Kick-off for the game is 10am Irish time.
