There is one change in the second row as Monivea native Conor Kindregan gets the nod alongside the senior-capped Michael Kearney. The back row remains unchanged with Eoin McKeon again linking up with David Heffernan and Eoghan Grace.
Buccaneers out-half Jack Carty will miss his former school Marist College's push for a first Connacht Schools Senior Cup since 1977 as he captains the Connacht 'A' side from number 10.
Carty is joined at half-back again by former Leinster Academy scrum half Dave Moore.
The centre partnership also remains unchanged with Galwegians pair Tadhg Leader and Brian Murphy retaining their starting places.
He joins former Cardiff Blues wing James Loxton and Matthew Jarvis in the back-three. Loxton is making his return after injury forced him off the pitch against the Ospreys in September.
Speaking ahead of the game, Connacht 'A' head coach Nigel Carolan commented: "Last week's performance was disappointing but tomorrow gives us a chance to put things right against what is expected to be a strong Leinster 'A' team.
"All of these games will help our young guys in their development and exposure to this level of rugby which will only benefit them ahead of next year's British & Irish Cup."
