Australia number eight David Pocock will miss the rest of the Wallabies' Test series against England due to a fractured eye socket.
Pocock suffered the injury during the second half of his team's 39-28 loss to England in Brisbane on Saturday.
A veteran of 55 Tests, the 28-year-old has been ruled out of the remaining two Tests.
Wallabies coach Michael Cheika is yet to name a replacement, but Ben McCalman and Wycliff Palu appear most likely.
Australia are heading to Melbourne on Sunday ahead of the second Test at AAMI Park.
