Australian football chiefs are sending their top physiotherapist to England to get a second opinion on Huddersfield Town's assessment of Aaron Mooy's knee injury.
Football Federation Australia (FFA) says high performance co-ordinator Phil Coles will travel to meet with Mooy next week to personally assess the playmaker's injury.
Mooy's English Premier League club Huddersfield Town says the midfielder has been ruled out of action until the end of February - a period which covers Australia's Asian Cup campaign - after tearing the medial collateral ligament in his right knee last weekend.
But Australian coach Graham Arnold is clinging to hope that Mooy might be available for the latter stages of the Asian Cup, which starts early next month in the United Arab Emirates.
AAP understands Mooy is likely to be named next week in the Socceroos' 23-man squad for the tournament.
Changes to the squad due to injury can be made until the tournament starts, with Australia's opening game against Jordan on January 6.
The FFA says due to the significance of the cup, Coles will be sent to conduct an additional review on Mooy's injury.
Coles' visit to Huddersfield will coincide with an independent assessment of Mooy's knee next Friday.
Coles and the Socceroos' medical staff will then make a final determination regarding Mooy's capacity to play in the Asian Cup.
"We have agreed on this plan with Huddersfield Town and know that they are doing everything they can to manage Aaron's injury," Socceroos coach Graham Arnold said in a statement on Friday.
"However, with such an important tournament coming up for Australia we want to explore every option available to give Aaron the chance to feature for the Socceroos in the United Arab Emirates.
"Of course, 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 do so.
However, we are also committed to leaving no stone unturned in our attempt to have him available for us at the tournament."
Mooy, who was injured in an EPL fixture against Arsenal last weekend, had seemingly resigned himself to missing the Asian Cup.
"I'm gutted to be missing an important time for club and country," Mooy told Huddersfield's website.
"I'm also sad that this injury will rule me out of the Asian Cup. I'd like to wish the Socceroos all the best as they head to the UAE. I'll be supporting them from afar."
