Former Australia captain Michael Hooper has been ruled out of the Wallabies’ Autumn Nations Series clash against Wales on Saturday.
Flanker Hooper, who has won more than 120 caps, presented with concussion symptoms following Australia’s 13-10 loss to Ireland last weekend.
The Wallabies said that 31-year-old Hooper would return home on Thursday.
He is the latest player to be sidelined during a punishing European tour that has seen successive defeats against France, Italy and Ireland.
A number of his colleagues had already been ruled out of the Wales encounter in Cardiff, including centre Hunter Paisami, scrum-half Nic White and prop Taniela Tupou.
