Roy Coyle will take over the reigns at Glentoran for the fourth time in his career following the exit of Alan Kernaghan, who resigned in the wake of his side's shock League Cup defeat at Annagh United.
Coyle, who was in charge of the Glens between 1997 and 2006 before caretaker spells following the exits of both Stephen Young and Eddie Patterson, is also Director of Football at the club and will be involved in the appointment of the next permanent manager.
Kernaghan had been in charge for just under ten months, but had failed to improve the Glens results on the pitch - they lost three of their opening five league fixtures before last night's result.
Despite being allowed to make wholesale changes to the Glentoran squad this summer, including the signing of former Glasgow Rangers striker Nacho Novo, the former Republic of Ireland defender has resigned.
Following last night's defeat, the 49-year-old had appeared adamant that he would stay on in the job.
"It is a results business and I understand that, and we have had two or three poor results," he told BBC Radio Ulster.
"Tonight our performance was better than it has been, but our problem all season has been scoring goals.
"I feel the fans' frustration more than they would believe.
"They vented their feelings in an audible manner, but I cannot do that. I have to try to keep the players going and motivate them.
"That is my job and that is what I am doing."
