Contepomi to hit 50-mark for title-hunting Lions
Contepomi makes his 50th appearance for a Leinster side that shows three changes from the team that last week sneaked past Border Reivers to move top of the table.
Reggie Corrigan comes back for Ronan McCormack, Rob Kearney is given a chance on the wing instead of Shane Horgan, while Cameron Jowitt returns for Niall Ronan. Unlike Declan Kidney, Leinster coach Michael Cheika had the luxury of making choices for the game after all the main contenders were declared fit.
