Martin O'Neill has named his provisional squad for Ireland's March fixtures at the Aviva Stadium.
Brentford defender John Egan and Reading midfielder Liam Kelly recieve their first senior call-ups, while Newcastle United goalkeeper Rob Elliot returns to the squad for the first time in a year since being injured against Slovakia.
Also selected after many calls for his inclusion is Aston Villa midfielder Conor Hourihane.
Shane Duffy and Stephen Quinn miss out due to injury but Robbie Brady has been included, despite being suspended for the game against Wales.
Preston new-boys and former League of Ireland stars Daryl Horgan and Andy Boyle are also included alongside team-mate Aiden McGeady. The trio have recently turned in fine performances in the Championship.
Ireland are currently top of Group D in the 2018 World Cup qualifiers and they will be looking to pick up points against the Welsh, who are still in the hunt for qualification in third.
Ireland play Wales on March 24 and welcome Iceland on March 28.
