U21 boss King calls up Conors
Also included in the squad is Coventry City goalkeeper Michael Quirke, who receives his first Republic of Ireland international call-up, as does Preston midfielder Adam Barton, who previously made an appearance for Nigel Worthington’s Northern Ireland senior team in a friendly against Morocco last November.
King said: “This friendly is a key element to our preparation for the European Championships which begin on September 1 at home to Hungary in Sligo. We have made a number of changes, purely to look at as many of our players as possible ahead of the campaign.
