Niall O'Donovan will depart Munster Rugby this summer after a 28-year career with Munster and Irish Rugby.
Along with his 28 years as a coach and most recently as team manager with Munster , O'Donovan also represented the province as a player in the 1980s.
The Shannon clubman had a 16-year playing career as a number eight, contesting 11 Munster Senior Challenge Cup finals, and winning seven.
O'Donovan joined Munster as assistant coach in 1997 and helped the province grow into one of Europe’s top teams, reaching the final of the European Cup in 2000 and 2002.
After five years with the province, he moved on to the role of forwards coach with the Ireland men’s team in 2002. He helped Ireland to three Triple Crowns, in 2004, 2006 and 2007. The 2004 Triple Crown was Ireland’s first since 1985 and he also took on the role of acting head coach on the 2005 tour to Japan.
Interim head coach Ian Costello said: "Niallo has been one of the most widely respected figures in Munster Rugby for the past 28 years.
"Personally, it has been an absolute privilege to work closely with him for over a decade and I can’t thank him enough for the level of support he has given me and so many others that have been lucky enough to work with him at Munster.
"He represents everything that is good about the club, his passion, his values, his incredibly loyalty, and he is the first person that people turn to when they need help. What differentiates Niall from others is the deep level of care he shows every day for the people he works with. He will be hugely missed when he departs at the end of the season."
