The Irish team shows three changes to the side to take on Wales in the final game of the U-20 Six Nations Championship in Parc y Scarlets on Friday night (kick off: 7.10pm).
There are two changes in the front row, one positional, with Adam Macklin coming into the side at tight head prop from the bench, a move which sees Jack McGrath shift to the loose head side of the scrum and Paddy McAllister moving into the replacements.
The backline sees one change with Shane Gahan selected in the centre with Ian McKinley swapping places with Gahan to be named on the bench.
Ireland coach Allen Clarke said: "With Adam Macklin and Shane Gahan coming into the starting lineup, we have focused on improving the accuracy and usage of ball from our set piece.
"The response from the players after a below par performance against Scotland has been excellent and there is a strong determination to finish the six nations with a quality performance."
