Republic of Ireland midfielder James McCarthy will miss this summer's European Championships for family reasons, with James McClean included in the 23-squad announced today.

McCarthy’s father has been diagnosed with cancer and is currently undergoing treatment.

The news was confirmed as Ireland manager Giovanni Trapattoni named his 23-man squad for the tournament in Poland and Ukraine.

In a statement McCarthy said: "I have discussed this with the manager. He was very understanding and I thank him sincerely for that.

"I take this opportunity to re-affirm my complete commitment to playing for the Republic of Ireland. It is a huge honour and source of pride for me and my family."

Trapattoni spoke to McCarthy last week and said the midfielder told him he was not ready "psychologically" and preferred to stay at home.

The Italian said McCarthy would have been in the squad, but refused to say who benefited from his absence.

The other talking points from the squad announcement at the Aviva Stadium were the inclusion of Sunderland's McClean and Seamus Coleman being named on the stand-by list.

McClean's form since breaking into the Sunderland side this year has seen him overtake Coleman as the back-up wide man.

The four other players on the stand by-list are goalkeeper Darren Randolph, Paul McShane, Paul Green and Andy Keogh.

Elsewhere in the squad, there were few surprises with Trapattoni opting for three goalkeepers, seven defenders, eight midfielders and five strikers.

Trapattoni said: "I had the very difficult task in choosing this 23-man squad. Several players have proven their abilities to us during the qualifying campaign, and we are thankful to all who have played a part. However, we are happy with our choices.

"The stand-by list consists of very capable players who we would be happy to call upon if needed. The game against Bosnia in the Aviva Stadium will be the beginning of our Euro 2012 journey and it is important for the players to feel the energy from Irish fans before we go to our training camp.

"We will look to emulate the attitude and performance that brought us qualification, and push our limits further as we prepare for this tournament. We will be focused as we enter this important time."
