Johnny Sexton has recovered from a quad injury and will captain Leinster against Toulouse in Sunday's Heineken Champions Cup semi-final, while Devin Toner and Robbie Henshaw have also been named to start.
Coach Leo Cullen has made a number of changes from the team that lost last weekend against Glasgow Warriors for the Aviva Stadium clash.
Elsewhere in the backs Rob Kearney again starts at full-back, Jordan Larmour is again on the right wing but James Lowe comes in on the left.
Henshaw keeps his place in the centre but is joined this week by Garry Ringrose.
In the half backs, Sexton is partnered by Luke McGrath.
Toner and Seán O’Brien are the only two forwards retained from last week with Cian Healy, Seán Cronin and Tadhg Furlong starting in the front row, with Toner and James Ryan behind them in the second row.
Rhys Ruddock is selected at blindside with O’Brien again at openside and finally Jack Conan at number 8.
Meanwhile, Antoine Dupont will start at out-half for the Top14 leaders, while Romain Ntamack is named on the bench.
