Graham Burke has been rewarded for his scintillating start to the 2018 SSE Airtricity League season with a call-up to the senior men's setup.
Republic of Ireland manager Martin O'Neill has announced a provisional squad for the friendly games against Celtic (20 May), France (28 May) and United States (2 June).
In his last appearance in green, John O'Shea will captain the side against the United States on Saturday 2 June.

The three friendly games act as the final preparation ahead of the UEFA Nations League opener away to Wales on 6 September.
O'Neill has made space in his squad for three players (Matt Doherty, Declan Rice & Scott Hogan) who made their debuts in the recent friendly against Turkey.
Shamrock Rovers forward Burke is the latest player from the League of Ireland to be called up to the squad, following on from the previous call ups for the Dundalk trio of Andy Boyle, Daryl Horgan and Gary Rogers.
Also receiving their first senior call-ups are Peterborough United goalkeeper Conor O'Malley, Millwall midfielder Shaun Williams, and Preston North End forward Callum Robinson.
A number of players miss out due to injury, including: Robbie Brady (knee), James McCarthy (broken leg), Jonny Hayes (ankle) and Aiden McGeady (ankle). Burnley forward Jonathan Walters returns after a long injury lay-off.
Some players will drop out of the squad after the Celtic game, while others will only report into camp ahead of the trip to Paris to take on France in Stade de France and the home game against the United States on June 2.
