Roscommon have confirmed that Kevin McStay will be senior football manager for the county ahead of the 2017 season.
McStay was joint-manager in 2016 along with Fergal O'Donnell.
O'Donnell had resigned from that joint role in September, stating that "concerted effort has been made (outside of management and players) to undermine and disparage us."
Fellow Mayo man Liam McHale will form part of his backroom team, with others to be confirmed.
Nigel Dineen had pulled out of the running for the manager's role last Thursday after citing "strong reservations about the integrity of the selection and recruitment process".
"Roscommon GAA is delighted to announce the appointment of Kevin McStay as the Roscommon Senior Football Manager.
"At a special meeting of Roscommon GAA held tonight the club delegates confirmed the appointment of Kevin McStay as the Manager of the Roscommon Senior Team. He will be joined by a backroom team which will include existing selector Liam McHale and others to be named.
"County Chairman Seamus Sweeney wished Kevin the best of luck and said that it is now 'all systems go for Roscommon as we prepare for the 2017 season'.
"'All attention is now focused on the County Football Finals this weekend,' he added, 'and will soon move towards the FBD Connacht league and our 2017 Division One campaign which starts with a tough away game against Tyrone on Saturday 5th of February."
