IRFU Chief Executive Philip Browne has issued a statement following confirmation of Ronan O'Gara's decision to retire from playing professional rugby.
22 year-old Gregory Mahe, who joined from Lourdes this season as scrum-half cover, replaces Pichot.
Italy fly-half Diego Dominguez and France's South African-born centre Brian Liebenberg were passed fit for the trip to Limerick.
Liebenberg has been out for a month after twisting his knee while Dominguez returns after tearing a hamstring. Right wing Raphael Poulain, with a pulled calf muscle, is replaced by Thomas Lombard although Poulain is named on the bench bracketed with Stephane Glas.
"There's no question, it's going to take one mighty fight to stop Munster's pack putting their halfbacks Stringer and O'Gara in a position to run the game," said France Test prop Pieter De Villiers.
