Ireland's Kiwi coach Joe Schmidt was taken to hospital shortly after his team's thrilling 26-23 win over the Wallabies this morning, according to Irish media.
The Irish Times reported that Schmidt was unable to attend a post-match press conference after suffering a bout of appendicitis.
"He is just going to be assessed," said Les Kiss, Ireland's defence coach.
"He has had some pretty bad stomach pains during the day. He toughed out the game in true Joe quality."
Before heading overseas, Schmidt had coaching roles with Bay of Plenty and the Blues.
