Nathan Collins, Kieran Sadlier and Troy Parrott have all been named in Mick McCarthy 40-man provisional squad for next month’s meeting with Switzerland.
Ireland play their UEFA EURO 2020 European Qualifier against Switzerland on September 5, followed by a Three International Friendly against Bulgaria five days later.
There are first call-ups for Stoke City’s Nathan Collins, Doncaster Rovers midfielder Kieran Sadlier and Tottenham striker Troy Parrott.
Crystal Palace midfielder James McCarthy returns to the squad for the first time under McCarthy and may make his first appearance since October 2016.
“I don’t know what’s going to happen between now and the next couple of games” manager McCarthy told FAI TV.
“We’ve got Saturday games, Tuesday games, Saturday and then the Saturday before me meet up. Players could get injured before we meet up.”
With focus on the European Qualifier against Switzerland, McCarthy expects a tough game against the UEFA Nations League semi-finalists.
“Switzerland are a good side. They have been in the higher echelons of the top teams in Europe for the last number of years.”
