Martin O'Neill has announced his provisional squad for the Republic of Ireland's Nations League opener against Wales and the international friendly with Poland next month.
A number of senior players who missed the friendlies against Turkey, France and United States return, while Preston forward Callum Robinson has made the panel for the first time.
He got an Irish passport through his Monaghan-born grandmother. He featured for an Ireland XI in the Scott Brown Testimonial in May.
There is also a first senior call-up for goalkeeper Sean McDermott, who plays for Kristiansund BK in Norway's Eliteseruen.
The 25-year-old qualifies through his Donegal-born father and has represented Ireland at Under-17, U-19 and U-21 level.
O'Neill says he wants to call up Dundalk winger Michael Duffy but must wait until FIFA approve his international clearance to switch allegiance from Northern Ireland to the Republic.
Injury has ruled out Everton midfielder James McCarthy (leg), Robbie Brady, (ankle) Scott Hogan (groin), and Preston North End's Sean Maguire (hamstring)
The Ireland squad will report into camp on Sunday, September 2, before travelling to Cardiff on Tuesday, September 4, for the game against Wales.
The squad will then travel on to Poland ahead of the game on Tuesday, September 11.
