Skipper Leo Cullen partners Malcolm O'Kelly in the second row with Elsom lining up in the back row alongside Shane Jennings and Jamie Heaslip.
In the back-line, Chris Whitaker partners Jonathan Sexton at half-back with Shane Horgan starting on the right wing, Luke Fitzgerald on the left and Girvan Dempsey at full-back.
Supporters are encouraged to use public transport on Sunday as there will be no parking at the RDS because there are other events taking place.
Gates open at 5.30pm. This game is a sell-out and there will be no tickets on sale on the day.
