Head Coach Leo Cullen confirmed this morning he is returning to New Zealand for personal reasons.
McQuilkin is a former Leinster player and captain and was also defence coach under Michael Cheika as part of the backroom team that brought a first ever Heineken Cup to the province in 2009.

Leinster Rugby Head Coach Leo Cullen said: “"This is very sad news for Kurt and his family and our priority is supporting Kurt in his decision as best we can.
"He will be with us for a few more weeks but after that he will head back home with our very best wishes in very trying circumstances and with the thanks of everyone at Leinster Rugby for his stellar contribution over the last 12 months.
"The process of replacing Kurt has already begun but right now our focus is on Kurt and ensuring that his move back home is as seamless as possible."
We wish Kurt McQuilkin and his family all the best as they return home in the coming weeks, Slán abhaile... pic.twitter.com/UmF6VGiomW— Leinster Supporters (@OLSCRugby) August 17, 2016
