Ireland assistant head coach and national fast bowling lead, Rob Cassell, will leave his post in the coming months to take up an opportunity within a franchise team in the Indian Premier League.
Australian-born Cassell joined Cricket Ireland in 2017 after a five-year stint in a similar role with South Australia.
He has worked alongside head coach Graham Ford during a period of transition for the senior squad, working closely with frontline bowlers and emerging talent coming through the performance pathway.
He will continue in his role at Cricket Ireland until mid-March after the Afghanistan T20I series in India.
Cassell said: "It’s been a fantastic experience working within Irish cricket over the last three years - it’s certainly a time my family and I will look back on very fondly.
"It’s been exciting to play a part in Ireland’s journey from Associate to Full Member, and to watch the steady improvement in performance across all formats over that time."
"However, the opportunity to work in the IPL has arisen and whilst I was hopeful of continuing my role with Cricket Ireland long term and combining this with the IPL position this was not possible given the upcoming series against Zimbabwe and Bangladesh clashing during the IPL window.
"As the group embark on a very busy summer of cricket I leave with a heavy heart, some great memories, and I wish the players and staff the best of luck as the group builds towards the T20 World Cup."
Richard Holdsworth, performance director at Cricket Ireland, said they will look to source a replacement very soon: "Rob has been a great asset for Cricket Ireland and we are sorry that he is leaving. His contribution and commitment over the last three years have been outstanding, and he has been instrumental in the development of several of the now first-team bowlers that are beginning to make their mark on the international stage.
"Given the nature and profile of the IPL, the attractiveness of working within one of the franchises is understandable and we wish Rob well with the move."
"We have an incredibly busy year ahead and will look to advertise the role immediately, given the upcoming tours and important home schedule – as well as a World Cup approaching in October."
