Ireland's U20 side continue their quest for a Grand Slam this weekend as they travel to Parc Eirias, Colwyn Bay and head coach Nigel Carolan has made a few adjustments to his side to face Wales.
Jordan Larmour will wear the number 15 jersey, switching from the wing where he has featured for Ireland's opening three games.
Tommy O'Brien moves from centre to the right wing and captain Calvin Nash will line out on the opposite flank.
Jack Kelly returns from injury to join Ciaran Frawley in midfield in a new centre partnership. Jonny Stewart partners number 10 Bill Johnston and will line out at scrum-half.
Tadgh McElroy lines out at hooker and is joined by props Joey Conway and Charlie Connolly in an unchanged front row.
Fineen Wycherley partners Oisin Dowling in the second-row. Gavin Coombes makes his first start in the back-row, alongside Paul Boyle and Number 8 Caelan Doris.
"The management team are very happy with how the side is progressing and developing so far in the Championship, but there is another big test ahead of us this Saturday in Colwyn Bay," Carolan said on Thursday afternoon.
"Wales have been going well in the competition, and despite a loss to England, they had a very big win against Scotland in the last round so they will be coming into this game full of confidence.
"We've had a good two week build-up to this game and had another good day with the senior side last week, so for us it's now about getting out there and putting in a performance."
