Wallabies Rugby World Cup squad members Nick Frost and Carter Gordon have been ruled out of the remainder of the tournament through injury.
Frost suffered a right knee joint injury in the side's 20-point win over Portugal on Sunday, with scans confirming he would be unavailable for selection if the side were to progress to the quarter finals.
Gordon, 22, picked up a knee cartilage injury at training last week which will see him return to Australia to being rehabilitation as soon as possible.
Wallabies head coach Eddie Jones said: "We're disappointed for Nick and Carter that their seasons have ended through injury."
"Nick showed great courage to play through significant discomfort against Portugal, while Carter has earned valuable experience during his first year as a Test player.
"We wish both of them a quick and successful recovery and to watching them continue to improve during Super Rugby Pacific next year."
Any medical replacements will be communicated in due course.
