Table-toppers Leinster, who have won their last three Magners League encounters (home to Connacht, away to Ospreys and then away to Munster in Musgrave Park)
Shane Horgan misses the game with the rib injury sustained last weekend, but the squad does include a number of experienced backs such as Brian O'Driscoll, Gordon D'Arcy, Girvan Dempsey and Felipe Contepomi who is the competition's fourth top points scorer of all time (with 611 points).
In the pack, the initial selection panel remains the same from last week so that means that the likes of Leo Cullen, Bernard Jackman, Malcolm O'Kelly and Ollie le Roux could come into contention.
The team is expected to be named on Sunday afternoon.
The game is expected to be a sell-out with around 17,000 tickets already sold. Supporters can purchase tickets visit the Leinster Rugby Store (Donnybrook) or Spar (Donnybrook) while a limited number of packages can also be bought online on www.leinsterrugby.ie
