Ireland Euro 2012 Squad
In a statement issued by the Football Association of Ireland, McCarthy said: "I have made the very difficult decision to withdraw my name from selection from the Euro 2012 squad following the diagnosis of my father with cancer and an ongoing requirement for treatment.
"I have discussed this with the manager. He was very understanding and I thank him sincerely for that. I take this opportunity to reaffirm my complete commitment to playing for the Republic of Ireland. I would like to wish the manager and my team-mates every success at the tournament and hope that Irish fans can understand the reason for my decision at this difficult time."
