Ballymena Academy's Bruce Houston links up at half-back with Harlequins U-18 regular Englefield, and Ballynahinch hooker Claytan Milligan, who touched down twice in the second match against Japan, combines with Cistercian College Roscrea duo Josh Wycherley and Michael Milne in the front row. It will be Milne's third start at tighthead.
Another Roscrea forward, Luke Clohessy, and UCD's Charlie Ryan are also set for their third starts of the series, featuring in the back row and second row respectively.
IQ Rugby's Ciaran Booth, who impressed in the Ireland U-18 Clubs & Schools side's two wins over Canada U-19s, will pack down alongside Ryan, while Scott Penny and number 8 Azur Allison, who captains the Ireland U-19s for the second time, complete the loose forwards trio.
Tierney's charges will face France again at the home of Connacht Rugby next Saturday (kick-off 2.30pm). Classed as the French Under-20 Development squad, they had a recent outing against Romania, winning 41-7, and will play Scotland in Edinburgh after their two encounters with Ireland.
