Penrith-born centre Will Addison has missed out on a place in Ireland's 44-man training squad for their pre-World Cup training camps.
Addison, who joined Ulster from Sale last summer and qualifies to play for Joe Schmidt's side through his mother, has not featured since January after undergoing a back operation.
Munster duo Mike Haley and Jean Kleyn are the only uncapped players included in the squad. Haley joined Sale last summer and is available on account of his maternal grandmother. The 24-year-old full-back played on the England Saxons' tour of South Africa in 2016 and was picked in training squads by Eddie Jones, without being capped.
Kleyn, a 25-year-old second row, qualifies for Ireland on residency grounds after swapping South Africa's Stormers for Munster in 2016.
Ireland play four warm-up games against Italy, England and Wales in August and September.
Schmidt said: "There were some very close calls in selection and it's always a challenging process because we know how hard the players work."
