Australia say they are going to”leave no stone unturned” as they attempt to possess Huddersfield’s Aaron Mooy readily available for the Asia Cup in January.
The midfielder has been eliminated until February later he ripped the lateral collateral ligament in his knee.
But Football Federation Australia said it could conduct its own appraisal.
“With this an important championship coming up you wish to explore every option available,” Socceroos head coach Graham Arnold said.
Arsenal on 8 December, injured in Huddersfield 1-0 defeat the 28-year-old, who has 39 caps.
The FFA said it sent its senior physiotherapist to the UK to conduct its own additional review of the injury of Mooy.
“Obviously, Aaron’s long-term career and fitness remains our primary concern and we will not rush him to return to match play before he is safe and confident to achieve this, but we are also focused on leaving no stone unturned in our effort to have him available for us at the championship,” Arnold explained.
“We have decided on this plan with Huddersfield and understand that they are doing what they can to manage Aaron’s injury”
The Asia Cup, which occurs in the United Arab Emirates, begins about 5 January and the very first game of Australia is against Jordan on 6 January.
Speaking on Wednesday Mooy, who’s launched 1-5 days for the Terriers in the Premier League this season, said:”I am gutted to be overlooking an important time for golf and country”
