The Westmeath man was a 53rd minute substitute in win over Fiji.
Ireland yesterday secured their place in the semi-finals at the World under-20 Rugby Championship with the help of Westmeath's Ronan Foxe.
The Kilbeggan man was a 53rd minute substitute in South Africa.
Richie Murphy's side ran in seven tries against Fiji to claim a 47-27 win and seal top spot in Group B after England and Australia played out a draw.
Ireland wore black armbands and a moment's silence was observed before the anthems following the heart-breaking death of scrum half Jack Oliver's father Greig.
The Grand Slam champions will play tournament hosts South Africa in Sunday's opening semi-final at Cape Town's Athlone Sports Stadium, with kick off at 3.30pm.
