Tom Rogic will miss January’s Asian Cup with Socceroos coach Ange Postecoglou revealing he will undergo further surgery on his troublesome groin.
The 21-year-old missed the recent World Cup through injury and hasn’t played a competitive game since.
And Postecoglou revealed on Thursday Rogic was likely to be unavailable for the Asian Cup after confirming the classy midfielder went under the knife again to try and fix the long-standing injury.
"Tommy has had a little bit of a setback and my understanding is that he's had to have another operation which will mean another lengthy absence," the Socceroos boss said.
"That probably rules him out of Asian Cup calculations, from what I understand. He's still got a fair bit of work to do in rehab.
"Our medical department has been speaking to him and they've been giving me regular updates. It's disappointing for him because he wants to get back playing."
Postecoglou said it was now up to Celtic to ensure Rogic gets back to full fitness as soon as possible.
"He's got a club coach and a club environment and we'll certainly provide him with all the support we can but from my perspective, we've got a lot of footballers who are injured at the moment and we don't know who will miss the Asian Cup," Postecoglou said.
"It’s not about me trying to console players who are missing out.
“They've got club coaches, their focus should be on their coach and, beyond that, when they're playing regularly, they'll come onto my radar."
Despite the blow the absence of Rogic will undoubtedly be to the Socceroos hopes of winning the Asian Cup on home soil, Postecoglou said his job was to ensure his team doesn’t revolve around individuals.
“I don't want to be in the position where we're just relying on one or two players and that's the process we're going through now. Injuries are just part of a footballer's journey," he said.
"We've got to protect ourselves so that when players get injured, we've got other options. To be fair to Tommy, he hasn't been in calculations for quite a while.
“We tried to get him up for the World Cup but he hasn't played in the last six or seven games. I think the best thing now for him is his rehab, making sure he's fit and to start playing football again.
"Once he starts playing football again, he'll come under our radar."
