Ulster centre Stuart McCloskey has been called up to the Ireland squad in New Zealand.
He'll replace injured provincial teammate, James Hume, who joins Iain Henderson in missing the remainder of the tour.
Connacht's Mack Hansen and Finlay Bealham are isolating due to COVID-19 but captain Johnny Sexton could still feature in next week's second test.
It was thought the Leinster out-half would face 12 days out after failing a head injury assessment in this morning's 42-19 defeat to the All-Blacks at Eden Park.
But the Irish head coach Andy Farrell says Sexton passed another assessment after the match.
