Also making their seasonal bow, is fellow internationals Rob Kearney who starts at full back and Devin Toner who partners Mike McCarthy in the second row.
With Kearney returning to full back Zane Kirchner moves to the right wing with Darragh Fanning again selected on the left wing. The St. Mary's club man has now started all four of Leinster's games this season.
Brendan Macken starts at outside centre with Ian Madigan selected at inside. Madigan came on at inside centre for Noel Reid after only 40 seconds of last week's game against Glasgow. Matt O'Connor confirmed yesterday that Reid's ankle injury is not as bad as first expected and expects him to be back within a number of weeks rather than months.
Isaac Boss, who made his 100th appearance for Leinster last weekend, starts again at nine with Jimmy Gopperth selected as his half back partner.
After his try scoring performance off the bench last week Jack McGrath starts at loose head with Mike Ross on the other side of the front row. Sean Cronin starts at hooker.
Toner and McCarthy are in the second row, while in the back row, Dominic Ryan, Shane Jennings and Jamie Heaslip complete the pack.
Tickets to the game are still available at www.leinsterrugby.ie/tickets or can be bought on the day with the ticket office open from 10.00am.
