IRFU Chief Executive Philip Browne has issued a statement following confirmation of Ronan O'Gara's decision to retire from playing professional rugby.
The selected Munster pack shows just two changes to the side that started against Benetton Treviso in round two of the Heineken Cup.
The continued absence of Marcus Horan provides a first Heineken Cup start for Springbok prop Wian du Preez, while John Hayes, who missed the Treviso game through suspension, returns on the tighthead side of the scrum at the expense of Tony Buckley.
Jerry Flannery, who was named in the extended squad, misses out because of what the Munster management describe as 'a slight Achilles problem.'
In the back-line, coach Tony McGahan has opted for a Lifeimi Mafi-Keith Earls midfield combination, while Denis Hurley, after a short but impressive role as a replacement against Ospreys last week, edges out Ian Dowling on the left wing.
Meanwhile, Perpignan have made five changes to the team that secured a 29-3 victory over Montpellier in the French Top 14 Championship last weekend.
Winger Farid Sid returns from injury, with centre David Marty, English prop Perry Freshwater and back row duo Yoann Vivalda and Yannick Parent all coming back into the starting line-up.
Number 8 Henry Tuilagi, out-half Nicolas Laharrague and winger Julien Candelon are notable absentees due to injury, but the Catalans still boast a strong selection - that strength most visible in the centre partnership of Marty and Maxime Mermoz.

Pre-Match Quotes: Paul O'Connell (Munster) - "Our form is probably a bit of a concern. We'd rather be playing great rugby, rather be flying along in the Magners League. I suppose we've struggled a little bit. We've had injuries.
"I suppose that was our big strength last year in that it didn't matter who pulled on the jersey - we performed. And that's something we need to look at and something we need to get right.
"The main thing we always do is try and focus on ourselves. When you get too bogged down and too focused on other teams you end up not playing.
"In that Ulster week it was all about our performance and that's why we produced the game we did on the day.
"The Ulster game for us was a great game to get going with back home. We were flying high that day.
"We were just concerned about ourselves and it'll be the same this weekend.
"The main priority will be our own play and how we perform and the intensity we play at. Sure we'll look at their strengths. And address those strengths. But we have to focus on ourselves first and foremost."
Nicolas Mas (Perpignan) - "After our faux-pas against Benetton Treviso in Round 1, we compromised our chances to qualify, but luckily a victory against Northampton Saints has helped us stand second in our pool behind Munster so all is not lost.
"We really made things difficult for ourselves and now we have no choice but to win these back-to-back games against Munster.
"It would be a real achievement for us to go and beat Munster but our ambitions are still there and we want to reach the quarter-finals.
"A huge challenge awaits us - especially when we go to face them on their home turf. Thomond Park is like a fortress and a very difficult ground at which to play.
"Munster are a great team, well used to competing in the Heineken Cup and they always turn up on the day as a fully committed team.
"I know that because I have played against them in two previous Heineken Cup tournament, in 2002 and 2006, and they are very difficult to face.
"Their pack is very strong and their three-quarters are fantastic players but, above all, they have an excellent metronome operator in Ronan O'Gara. Make no mistake, we know what to expect and we know we are in for an extremely tough challenge."
