Ludik will start on the left wing opposite Mark Keane, who played for Ireland U19s in last week's international versus Japan, on the right flank. Mark Best, a constant feature throughout the British & Irish Cup campaign which saw the Ulster men reach the quarter-final stage, completes the back three.
Callum Patterson will start at outside centre, pairing up with McCloskey in the midfield, while the familiar partnership of Brett Herron and Dave Shanahan continue at half-back.
John Andrew will captain the side from hooker, where he is joined in the front row by Tommy O'Hagan and Ricky Lutton. John McCusker who, like O'Hagan, made his breakthrough in the All-Ireland League with Rainey OB RFC, is positioned in the second row with Pete Browne.
Joe Dunleavy, another product of the club system, will start at blindside flanker with former Ireland U20 internationals Conall Boomer and Greg Jones taking up the other loose forward positions.
