Mick McCarthy has named his Ireland squad for the forthcoming European Championship qualifier against Switzerland and the friendly with Bulgaria.
There are first call-ups for Stoke City's Nathan Collins, Doncaster Rovers midfielder Kieran Sadlier and Tottenham striker Troy Parrott.
Also included in the squad is James McCarthy - the Crystal Palace man hasn't played for Ireland since October 2016.
Manager McCarthy said the squad will be reduced closer to the September 5 qualifier after the next few rounds of club fixtures:
"I dont know what's going to happen between now and the next couple of games. We've got Saturday games, Tuesday games, Saturday and then the Saturday before me meet up. Players could get injured before we meet up," he told
Looking ahead to the clash with the Swiss, McCarthy said:
Switzerland are a good side. They have been in the higher echelons of the top teams in Europe for the last number of years.
Ireland currently top the group but they have already played Gibraltar twice and both Denmark and Switzerland have games in hand over Mick McCarthy's men.
