Munster and Leinster have both named their teams for their respective Guinness PRO12 inter-provincial derbies.
Leo Cullen has made eleven changes in total from the Munster game with a number of players back involved after recent injuries with Luke McGrath (knee), Johnny Sexton (quad) and Ben Te'o (concussion) all returning to the starting XV while a further eight players come in to start.
In the pack Jack McGrath is once again selected at loosehead prop after his try scoring performance last weekend with Marty Moore coming in from the start this weekend.
It's a completely new back row with captain Rhys Ruddock leading the charge from blind side flanker and Josh van der Flier selected at open side. Finally Jordi Murphy starts from number eight.
In the backs Rob Kearney starts at full back in only his second Guinness PRO12 game of the season, while Dave Kearney is named on the left having been an unused substitute in the win over Munster last Sunday.
Ben Te'o returns from injury and takes over the inside centre jersey from Luke Fitzgerald with Garry Ringrose outside him at 13.

Head Coach Anthony Foley makes seven changes to the starting XV for Saturday's round 11 PRO12 encounter.

Mark Chisholm is introduced in the second row and with Tommy O'Donnell returning to the backrow Jack O'Donoghue makes the positional switch to blindside, with Captain CJ Stander continuing at 8.

Replacement scrumhalf Duncan Williams is in line to become the ninth player in the current squad to reach the milestone of 100 appearances for the province if sprung from the bench this weekend.
