Leinster's "A" team, coached by Colin McEntee and Richie Murphy, includes a number of promising young players, as well as some established senior squad members in hooker Brian Blaney and lock Cameron Jowitt.
The starting line-up includes twelve players who have seen Magners League action this season, among them centre Michael Berne, who has recovered from a fractured cheekbone in a timely boost to the province.
Ross McCarron starts in a speedy-looking back three which includes Fionn Carr, who made his senior debut last week against Glasgow, and Ireland Under-20 Grand Slam full-back Felix Jones, who is set for a winger's role.
In the pack, another former U-20 international Cian Healy, fresh from scoring his first senior try for Leinster against Glasgow, lines up in the front row alongside the aforementioned Blaney and Argentinian prop Juan Francisco Gomez.
The Leinster "A" replacements bench includes a number of up-and-coming Academy players, amongst them Richie Sweeney, who impressed in pre-season, Paul O'Donohoe, Shane Monahan, Ruaidhri Murphy, Kevin Sheahan and Kyle Tonetti, who were all members of the Ireland U-20 Grand Slam-winning squad of 2007.
