The Dublin County Board last night released a statement saying that under-21 and senior footballer Shane Carthy was being treated for depression.
Carthy was man-of-the-match in the under-21 Leinster final but didn't feature in their semi-final victory over Cavan.
The All-Ireland under-21 football final takes place tomorrow with Dublin up against Roscommon in Tullamore.
Dublin County Board chief executive John Costello, said: “The Dublin County Board, the Dublin senior and U21 football management teams would like to report that senior and U21 footballer Shane Carthy is currently receiving treatment for depression.
“We are satisfied that Shane is receiving all the necessary support and are happy to report that he is making progress with his illness.
“We would ask all units of the media and indeed the wider GAA family to support Shane and his family on this matter and to respect their privacy.
“We would directly appeal to reporters not to contact the family or family friends. Shane is a 19-year-old dealing with a serious problem and we are confident that his and his family’s wishes will be respected.
“We would like to thank both football management teams and panels and the Naomh Mearnóg club for their support for Shane during this difficult time.
“Over the past few years the media and GAA players have been to the forefront in helping to promote positive messages about mental health and this is to be very much welcomed and supported.”
