He has been capped 172 times since making his debut in 1998 and been involved in all of Munster's major triumphs.
Coach Tony McGahan was clearly more than happy whern asked for his reaction to the news. "We're obviously delighted that Donncha has agreed an extension of his contract. I believe it's a massive boost for Munster given the strong interest there was in him from overseas clubs with far greater financial resources than Munster."
"He's a hugely ambitious competitive character," McGahan continued, "and I think this sends a clear message concerning that ambition and where it will be best served. Here in Ireland with Munster. "I think it's also a very encouraging sign for younger players to see a player of his calibre and universal appeal showing the loyalty and commitment he has done by agreeing this new deal. I look forward continuing to work with him. This is certainly good news for Munster Rugby."
The player himself speaking from the Ireland team hotel in Dublin where he is preparing for his 65th Ireland cap said "As players we are so well looked after by both the national and provincial management teams and I feel incredibly privileged to be able to play the sport I love for both Ireland and Munster. Munster is my home province and the decision to continue my career here was an easy one when you consider the standard of players in the squad and the incredible support I have received from both the fans and my family. My focus now is to try and perform as well as I can to help Munster and Ireland to be successful."
