Sydney - The Wallabies have lost backs Pat McCabe and Digby Ioane with injuries for the remaining two Tests against the British and Irish Lions, team officials said on Monday.
Both players sustained injuries during Saturday's 23-21 loss to the Lions in the first Test in Brisbane which will require further examination by specialists, a team spokesman said.
Centre McCabe re-injured his neck which he first damaged on last year's European tour and will have further scans and consult with specialists this week.
Winger Ioane damaged his right shoulder and will also require further follow up scans, with surgery a possibility, the spokesman said.
In a further injury blow to the Wallabies, fullback Berrick Barnes will miss Saturday's second Test in Melbourne after he was concussed in the first half of last weekend's match.
His recovery is being managed according to the IRB concussion guidelines and Barnes will not be considered for the second Test, although he may be considered for the third game in Sydney.
The news was better for inside centre Christian Lealiifano, who is making an excellent recovery after he was concussed in making a tackle on Jonathan Davies in the opening minute of the first Test.
Lealiifano has made good progress and is expected to be able to be considered for selection for this weekend.
Outside centre Adam Ashley-Cooper, who underwent scans on his shoulder after the Test in Brisbane, is also improving with medical staff confident he will be available for the second Test following further rehabilitation of the injury.
The Wallabies team will be named on Thursday.
