The Ireland squad for this summer's World Twenty20 qualifiers will be announced on Monday but it will not include Ed Joyce or Tim Murtagh.
The two experienced county professionals both told the Ireland selectors they did not want to be considered and have announced their retirement from T20 internationals.
Joyce had intimated during the World Cup finals in March that he would give up the shortest format to concentrate on helping Ireland on the pathway to Test cricket in the Intercontinental Cup while, like Joyce, Murtagh no longer plays T20 cricket for his county, Middlesex.
So although neither decision is a surprise, Ireland's chairman of selectors Alan Lewis said: "Wise men make the right decisions at the right time and this is no different. I can't speak highly enough of both.
"They are hugely valuable to us in the longer formats (they will also continue to play one-day internationals) and when you consider their county commitments their decision is fully understandable."
Joyce, a veteran of Ireland's last two World Twenty20 campaigns, will still be missed by Ireland. He retires at the top of the batting averages in the shortest format - 33.75 - while Murtagh took 18 wickets in his 17 T20 games at just over 21 runs each.
Meanwhile, Co Galway are now expected to be given the go-ahead to play Waringstown in the second round of the Irish Senior Cup after telling Cricket Ireland that all three Terenure registered players, who played in the victory over Fox Lodge last Saturday, reside in Munster.
The governing body has been gathering information since it was revealed that Terenure's New Zealand professional, Ben Speake - who hit a match-winning 87 not out - and two of his team-mates turned out for Galway, but unless proven otherwise, an address in Munster is enough to play for a Leinster team in the competition.
A final decision is expected to be made today
