Ireland U20 coach Mike Ruddock has made three personnel and once positional change to the team to face France in the Stade Maurice Trelut on Friday night.
The UCD half-back combination of Nick McCarthy and Ross Byrne are replaced by Jack Cullen from Bruff and Lansdowne's Conor McKeon, respectively.
Cian Kelleher switches from the wing to full-back with David Busby taking a place among the replacements and Alex Wootton coming into the side on the wing.
Sean O'Brien continues as captain and is again partnered by Ross Molony in the second row. A win for Ireland U20 will secure a top half finish and deny the French the grand slam.
"The result against Italy got us back on track and this weekend we face a strong French outfit that are going for the Grand Slam,” said Ruddock. “We have brought in a couple of new faces and there is an opportunity for these players to show what they can deliver against quality opposition.”
