Ireland have announced that Munster hooker Michael Sherry will travel to New Zealand as precautionary cover for the injured Rory Best.
Best is still being assessed as he recovers from a shoulder injury he suffered in Ireland's match against Italy on Sunday.
Ireland kicking coach Mark Tainton confirmed on Tuesday that Best was doubtful for the quarter-final match against Wales on Saturday.
"His chances at the moment, they're long. He's doubtful for this weekend but he's not ruled out of the competition," Tainton said.
The 23-year-old Sherry, who will join the team in Wellington on Thursday, has yet to make his international debut for Ireland.
