Returning head coach Andy Farrell has included captain Caelan Doris in his Ireland squad for the autumn internationals, but Joe McCarthy misses out.
Doris, who has not played since undergoing shoulder surgery in early May, recently returned to Leinster training, but it remains unclear if he will be fit to face New Zealand in Chicago on 1 November.
Lock McCarthy, however, was not considered after failing to recover from the foot injury he sustained during the first British and Irish Lions Test against Australia in July.
Ulster forward Cormac Izuchukwu and Munster wing Calvin Nash also miss out because of injury, while full-back Hugo Keenan had already been ruled out after undergoing hip surgery following the Lions tour.
Leinster prop Paddy McCarthy - Joe's younger brother - is the only uncapped player in the 34-man squad, but the Irish Rugby Football Union [IRFU] says uncapped Munster duo Edwin Edogbo and Brian Gleeson and once-capped Connacht wing Shayne Bolton will travel to Chicago as "cover".
