Socceroos coach Graham Arnold said rising star Daniel Arzani is in good hands, after it was revealed the 19-year-old had torn his cruciate ligament on debut for Celtic.
Arzani will be reviewed by a knee specialist in Europe early next week, which will determine the full extent of his injury and the prognosis moving forward.
But he is almost certain to miss the rest of the season and Australia's campaign to retain their Asian Cup title in January.
Football Federation Australia (FFA) performance staff have been in contact with medical staff at Celtic, and with the player directly, to monitor his current injury situation.
Arnold said: “We have great confidence in the staff at Celtic FC to manage Daniel’s injury appropriately.
"FFA’s performance team will continue to liaise closely with Celtic and Daniel to provide Daniel with whatever assistance he requires.”
The fledgling Socceroo went down in agony and was stretchered off the pitch after slipping awkwardly during the club's midweek 5-0 thrashing of Dundee.
Overnight, Celtic coach Brendan Rodgers confirmed the worst fears of Socceroos and Celtic fans.
At a press conference in Glasgow, Rodgers admitted two of his players had succumbed to serious injuries.
"Unfortunately, it looks like cruciate injuries for both Daniel Arzani and Eboue Kouassi," he said. "It's disappointing for them because they've been working hard to get into the team."
