Giovanni Trapattoni has included 23 players that will travel to Ukraine and Poland this summer, but the Latics man has decided not to be considered due to his father being diagnosed with cancer.
The Italian coach admitted that it was a difficult task in selecting his contingent, but believes his team can do well at the tournament.
“I had a very difficult task in choosing this 23-man squad,” Trapattoni told Sky Sports.
“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 standby list consists of very capable players who we would be happy to call upon if needed. The game against Bosnia in 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,” he concluded.
Squad in full:
Shay Given (Aston Villa), Keiren Westwood (Sunderland), David Forde (Millwall); John O’Shea (Sunderland), Stephen Kelly (Fulham), Stephen Ward (Wolves), Richard Dunne (Aston Villa), Sean St Ledger (Leicester), Darren O’Dea (Leeds), Kevin Foley (Wolves); Glenn Whelan (Stoke), Keith Andrews (West Brom), Keith Fahey (Birmingham), Darron Gibson (Everton), Damien Duff (Fulham), Aiden McGeady (Spartak Moscow), Stephen Hunt (Wolves), James McClean (Sunderland); Robbie Keane (LA Galaxy), Kevin Doyle (Wolves), Shane Long, Simon Cox (both West Brom), Jon Walters (Stoke).
