Sunday Game host Michael Lyster is reported to be sitting up in bed after a major heart scare at his home at the weekend.
The well-known broadcaster (60) was moved to a recovery ward in St Vincent's Hospital after spending almost two days in intensive care in the Mater.
"He's sitting up and doing well and we hope he will make a good recovery," a source said.
The Galway native and father-of-four has previously spoken about his first health scare in 2012 when he suffered heart failure towards the end of the GAA championship season.
At the time he thought he had a bad bout of the flu but, after presenting himself at Blackrock Clinic, tests showed his heart was operating "at maybe 15pc of its capacity," he said in a Late Late Show interview with Ryan Tubridy.
Lyster was forced to miss his RTE broadcasting duties at the weekend for only the second time in his career.
He previously missed one programme after the death of his mother Mary in 2010.
In an interview last month, Lyster spoke of his previous health problems.
"Everyone thinks they are indestructible but then you realise you are not and that health can so easily be taken away from you," he said.
"Actually, fellas who get heart attacks, their hearts would be in better shape than mine was. My heart was just gradually shutting down."
Last weekend his colleague Joanne Cantwell filled in on his Saturday programme while Daragh Moloney presented The Sunday Game and wished him well in the opening section.
"Our friend and colleague Michael Lyster was taken ill on Friday and he wasn't able to be with us today. We want to wish Michael all the best," Daragh said, before taking on the show.
