The Wallabies have announced a 31-man touring squad for the next round of The Rugby Championship in Argentina on Saturday.
Will Genia and Rob Horne have both been ruled out of the squad due to injury, following Australia’s four-point victory over the Springboks in Brisbane on the weekend.
Genia suffered bone bruising and minor cartilage damage to his knee, while Horne will return to Sydney with a calf strain.
Wallabies head coach Michael Cheika said: “It’s disappointing for Will and Rob to miss this upcoming Test. They have both made an outstanding contribution to the group this past two weeks, and will continue to remain part of the wider squad from afar.”
“Will is due to have some minor surgery this week and we are confident he will be available for selection for the Bledisloe Cup series.
“We have taken a conservative approach with Rob and the additional week off will serve him well going into the next stage of our campaign."
Nick Cummins and Nic White will join the squad as their replacements, with two further additions in hooker James Hanson and prop Tetera Faulkner.
They will return as official members of the 31-man squad, after being used as additional training squad players in the lead-up to the Springboks Test.
