Ulster players Tom Court and Darren Cave are notable omissions from Joe Schmidt's first Ireland squad, for a training camp next week.
Court is missing from the 42-man squad, with Cian Healy, Dave Kilcoyne and Jack McGrath the selected loose-head props.
Ulster players Rory Best, Tommy Bowe, Declan Fitzpatrick, Iain Henderson, Chris Henry, Paddy Jackson, Luke Marshall and Dan Tuohy are included.
There is also a place for uncapped Leicester back Niall Morris.
Court, 32, fell out of favour during former national coach Declan Kidney's final year in charge,
though he did start the Six Nations game against Scotland in February because of Healy's suspension.
Born in Australia, he was
called into the British & Irish Lions squad
during the summer as a replacement while on holiday in Brisbane.

But with Schmidt opting to call up uncapped 23-year-old Leinster prop McGrath, Court is left out of the training squad for the get-together at Carton House, in County Kildare, on Sunday and Monday.
Centre Cave and scrum-half Paul Marshall, Ulster team-mates of Court, are also omitted.
Three other Ulster players - Andrew Trimble, Craig Gilroy and Stuart Olding - are among a group of players not considered because of injury, along with Munster pair Tommy O'Donnell and Felix Jones plus Leinster prop Michael Bent.

Leinster's Brian O'Driscoll, 34, in his final year before retirement, is named among the backs along with long-time club and international centre partner Gordon D'Arcy.
Veteran Munster lock Donncha O'Callaghan is also included along with Leinster flankers Shane Jennings and Kevin McLaughlin but James Downey, Kieran Marmion and Jamie Hagan, who were part of Ireland's squad for the North American tour in the summer, miss out.
appointed as Kidney's successor in April,
said a number of the selections had been "very tight".
"The group is predominantly 'tried and proven' but with some newer faces as well," said the Ireland coach.
"It's an opportunity to get to know the players as well as an opportunity to have a look ahead and start to get a little bit of organisation done."
The get-together will be the beginning of preparations for the games against Samoa, Australia and New Zealand in November.
