Leinster have chosen nine of the team that started last season’s Champions Cup final as they look for revenge on La Rochelle in the pool stage on Sunday in Stade Marcel Deflandre (3.15pm KO Irish time).
Garry Ringrose and James Ryan co-captain the team for the first time in European competition. Hugo Keenan starts at fullback, with Jordan Larmour and Jimmy O’Brien named on the wings.
Ringrose is joined by Robbie Henshaw in the centre, with Harry Byrne and Jamison Gibson-Park completing the backline. Byrne is set to make his first start in the Champions Cup, following seven previous appearances from the bench.
In the pack, Sheehan is joined in the frontrow by Andrew Porter and Michael Ala’alatoa. Ryan packs down with Joe McCarthy in the second row, for the first time in an away European match.
After starting in the second row last week, Ryan Baird moves into the backrow where he is joined by Will Connors and Caelan Doris. Connors is set for his first European appearance in over three years.
Among the replacements, prop Thomas Clarkson and scrumhalf Ben Murphy are set to make their Champions Cup debuts.
