Tullow man Sean O Brien will captain Leinster for their PRO 14 game against Glasgow Warriors tomorrow.
Sean starts in the backrow with Josh Murphy and Caelan Doris either side of him.
Carlow man Ed Byrne also starts in the front row.
It is the last regular season home game to be played by Leinster in the Guinness PRO14 and sees them take on a Glasgow team that are also top of their Conference.
On the bench there is the potential for a seasonal debut for Will Connors.
Connors injured his ACL against Newcastle Falcons in the pre-season friendly back in August and has been out injured since. Should he come on he will become the 56th player used by Cullen this season.
