Farrell has named three tens in his travelling party for games against Australia in Sydney, Japan in Newcastle and New Zealand in Auckland with Sam Prendergast, Harry Byrne and Ciaran Frawley all making the trip.

Crowley finished the Six Nations as the undisputed first-choice out-half and would have been aiming to solidify that status Down Under. Now it falls to one of the other three to put their stamp on training and games in the weeks ahead.

Others unavailable due to injury were Ryan Baird, Shayne Bolton, Jack Boyle, Edwin Edogbo, Tom Farrell, Mack Hansen, Paddy McCarthy, Calvin Nash and Andrew Porter. Caelan Doris will again act as captain.

James Lowe, due to leave for club rugby in Japan, is another whose name is missing.

Farrell has opted for an experienced group, as expected, but there are three uncapped men in the party, all of them from Connacht, with Sam Illo and Billy Bohan pushing for caps in the front row and Sean Jansen coming off a superb season at No.8.

Bohan was part of the Ireland squad for the Six Nations earlier this season, while Illo and Jansen, who have featured for Emerging Ireland previously, have earned their first senior squad call ups.

A contingent of players from Munster, Connacht and Ulster have been training in Abbottstown this week while their Leinster counterparts focus on Friday’s URC final against the Bulls. The whole group will fly to Australia on Monday.

Farrell has already highlighted the need to hit the ground running.

“The experience of playing down under will be priceless for us and, even though we’ll be playing in front of largely partisan home crowds, we are also excited about playing in front of a huge Irish support.

“Their dedication to the team never ceases to amaze us and with a huge diaspora down under I’m sure we can count on a large Irish following in Sydney, Newcastle and then on to Auckland.

“For us, we are aiming to build on our positive performances during the recent Guinness Men’s Six Nations.”
