Australia forward David Pocock has been ruled out of the remaining two Tests of the series against England after fracturing his eye socket in Saturday's 39-28 defeat.
The number eight was injured in a collision as the Northern Hemisphere side won in Brisbane to clinch a rare win on Australian soil.
Pocock, 28, wrote on Twitter: "Gutted to be ruled out of the rest of the #AUSvENG series with a fractured eye socket. Disappointing but these things happen."
Coach Michael Cheika, meanwhile, said: "If we want to bring in almost a like-for-like player, then we'll go with Liam Gill. We have options with experience, so we're fortunate but it's disappointing to lose a player of David's quality."
Pocock, who is expected to be out for up to six weeks, will remain with the squad.
