JOHANN van Graan will leave Munster at the end of the season.
The South African, who was appointed as head coach in November 2017, is the second-longest-serving of the professional era.
Since joining in 2017 Munster reached two Champions Cup semi-finals, three league semi-finals, and a PRO14 final earlier this year.
“While I was at advanced stages in the contract process earlier this year, I took a step back and reconsidered my options, prioritising what’s best for my family, myself, and Munster Rugby," he explained in a Munster statement.
“My family and I settled well into life here, this is our home, and in an ideal world we would love to continue living in Limerick, but I’ve been looking at the bigger picture.
“After arriving during the 2017/18 season, I am now into my fifth season with this group and in putting Munster first I believe it’s the right decision for me to call time on my contribution and step away at the end of this season.
While we have achieved so much together, and still have over six months of the season remaining, I wanted any uncertainty about my future addressed as early as possible.
“Working with this coaching team, staff, and players we are always striving to do our best for Munster Rugby, and nothing will change on that front.

"Johann has been a valued addition to the province and integral to all the successes we have achieved over the past four years.
“His hands-on approach and tireless work ethic have ensured the structures are well in place for continued success and we know he will continue to deliver on all fronts for the remainder of the season.
“For now, we are working closely with the IRFU in looking to identify suitable replacements with the confirmed departures of both Johann and Steve (Stephen Larkham) next summer.”
During his time van Graan has provided much-needed stability across the High-Performance Centre further aligning the senior and academy structures with more visibility for the next generation of players.
Players such as Shane Daly, Gavin Coombes, Fineen Wycherley, Craig Casey, Thomas Ahern, and Ben Healy to name a few have all progressed in their careers during his tenure.
The former Springbok coach was the catalyst for securing the services of the World Cup-winning duo of RG Snyman and Damian de Allende while he also oversaw the recruitment of key signings such as Joey Carbery, Alby Mathewson, Mike Haley, and Simon Zebo.
