The Wallabies could be in line for a major boost with prop Taniela Tupou likely to be available for the second Test against England.
Tupou missed the first Test as he continues his recovery from a calf injury suffered during Super Rugby Pacific.
However, he could be thrust straight back into the starting side after Allan Alaalatoa departed the field in the first half with a concussion.
Under World Rugby's new concussion laws, players must sit out 12 days before returning, leaving the Brumbies skipper all but ruled out for Saturday's second Test.
The Wallabies will face England at 9.55pm Saturday.
Meanwhile, the All Blacks face Ireland in their second test match at 7.05pm Saturday.
