The selected squad features a number of players who took part in the O2 Challenge - the first rugby match at the Aviva Stadium - back in July.
Ballymena's Luke Marshall, who was named man-of-the-match in that game and recently made his Ulster debut, will start at centre, while Dungannon clubman Paddy Jackson and UCD's Peter du Toit have been paired together at half-back.
Up front, Daniel Qualter from Buccaneers will partner Ian Henderson of Queen's University in the second row.
Lansdowne's Jordi Murphy, who featured in the Ireland Under-20 panel last season, will captain the side from the openside flank.
Indeed, Murphy, his Lansdowne club-mate Martin Moore and UCD hooker David Doyle all played for Ireland at last summer's IRB Junior World Championship in Argentina.
