It's been switched because of an Ed Sheeran concert.
Leinster and Munster have agreed to switch the dates of their inter-pro meetings in the URC later this season.
Thomond Park had been set to host the derby between the sides on the weekend of May 22nd, but a move was required due to an Ed Sheeran concert at the Limerick venue on May 5th.
Munster say it's unlikely the pitch would be sufficiently recovered in the two weeks following the gig.
Leinster will now go to Thomond Park on the 2nd of April with Munster travelling to the Aviva Stadium on the last weekend of the regular season.
Commenting on the move, Leinster Rugby CEO Mick Dawson said:
“This was not a straight forward process by any means but the reality is that we were approached by the IRFU and Munster Rugby with a view to facilitating a switch in dates for the two games.
“We understand that there will be disappointment in particular amongst Leinster Rugby fans who have been planning for the game on April 2, but a solution needed to be found for that fixture in May with Thomond Park unavailable.
“The past few seasons have been difficult on us all and flexibility and working to find solutions in ever-changing scenarios has become the reality for all organisations and that is the case here also. We were faced with a dilemma and we worked hard together to find a solution that ensures that Leinster Rugby and Munster Rugby supporters will enjoy two great days out in Aviva Stadium and Thomond Park.
“We now have a full fixture list in the United Rugby Championship and in the Champions Cup with plenty of big games, and big interpro games at that, to look forward to.”
