Ciarán Comerford has stepped down from his post as manager of the Roscommon hurling team.
Comerford was in his final year at the helm of the senior team and was due to depart in September.
The former Laois and Borris-Kilcotton player was appointed Roscommon manager in November 2017.
Speaking after the announcement, Roscommon hurling board chairman Christy McDermott said: "I'd like to thank Ciarán for his efforts over the past two and half years with the Roscommon team.
"I fully respect the decision he has made as the Christy Ring competition will not now commence until much later in the year.
"Ciarán feels this is a more appropriate time to step down as it allows a new manager to prepare for the Christy Ring Cup and the new season which will follow on so closely.
"We had some good days, including our winning of the Division 3A National League last year."
A recruitment process for a new manager is now under way, with an appointment expected to be made by the end of the month.
