Leinster look to build on last week's bonus point victory over Ospreysand make nine changes for their trip to Cardiff Blues.
In the backs, Zane Kirchner and Dave Kearney continue at full back and on the left wing while Fergus McFadden returns from injury on the right wing for his first start since the Irish provinces over Treviso.
Noel Reid continues at inside centre but is partnered for the first time this season by Rory O'Loughlin who makes his first competitive start for Leinster having appeared as a replacement in two games.
Jamison Gibson-Park starts at scrumhalf with Johnny Sexton as captain from number ten.
In the pack it's a new front row with Jack McGrath, James Tracy and Mike Ross lining up, while behind them Mick Kearney is joined for his Leinster debut by Ian Nagle.
Nagle last played in the PRO12 in December 2013 for Munster against Scarlets in a 16-10 win.
In the back row two replacements from last week, Dan Leavy and Rhys Ruddock, start at blind side and number eight respectively, while Josh van der Flier starts at open side.
On the bench is Leinster Academy scrumhalf Nick McCarthy, UCD's Barry Daly and Jamie Heaslip.
