Both Leinster and Ulster have rung the changes for their Rainbow Cup clash at the RDS on Friday evening (LIVE on eir sport 1 from 8pm).
There are ten different faces in the home side's starting XV compared to the game against Connacht a week ago, while Ulster head coach Dan McFarland has made 12 changes to the team that started the 38-10 defeat to Munster in Limerick last Friday night.
Garry Ringrose, Dave Kearney, Ross Byrne, Luke McGrath and Josh Murphy are the only players to retain their places from Leinster's 50-21 win in Galway.
Jimmy O'Brien returns from injury at full-back, with Jordan Larmour on the wing and Robbie Henshaw in the centre.
Cian Healy, Sean Cronin and Tadgh Furlong start up front, with James Ryan returning to take his place alongside Ryan Baird in the engine room.
Caelan Doris makes a welcome return to action for the first time since February at number eight, with Josh Murphy and Josh van der Flier on the flanks.
Billy Burns and Dave Shanahan will combine at half-back for Ulster, with Robert Balacoune named on the wing. James Hume comes into the centre alongside Stuart McCloskey.
Eric O'Sullivan, Rob Herring and Marty Moore are named in an all-new front row, while Sam Carter comes in to partner skipper Iain Henderson in the second row.
