After reports Aaron Mooy could miss the Asian Cup with injury, two more Socceroos regulars in Robbie Kruse and Tomi Juric are also under injury clouds.
Kruse is currently sidelined with an abductor muscle tear that's seen him miss three straight games for German club VfL Bochum.
The injury-prone Aussie last played on November 12 and was rested from the Socceroos last friendly against Lebanon due to a minor injury.
Despite now being stuck in the stands, Kruse has had a solid season for Bochum scoring once and assisting twice across 11 appearances.
The Socceroos veteran faces fresh competition for his spot on Australia's left flank thanks to the emergence of fellow wingers Awer Mabil, Martin Boyle and Craig Goodwin.
Juric meanwhile has missed two consecutive games for FC Luzern due to an unspecified injury, according to Transfermarkt.
The 27 year old has started just three times this season in Switzerland with the Aussie snaring one goal across seven senior appearances.
A torn muscle fibre saw Juric miss the first two months of the campaign and he's faced some serious competition for his Socceroos spot in the process.
Graham Arnold handed Jamie Maclaren a start up front against Korea Republic last month before restoring Juric to his side for the next match against Lebanon.
This latest injury set back will do Juric no favours however as the Socceroos look to lock down a reliable goal scorer for the Asian Cup in January.
While Maclaren is fit, he has been used sparingly by Hibernian in recent weeks with the forward bagging just one goal across 13 appearances in Scotland.
