Australia is already without Aaron Mooy and Daniel Arzani for the tournament, with Mathew Leckie's involvement doubtful with a hamstring complaint.

Now Boyle has been ruled out of the Asian Cup campaign after contact to his knee in the 5-0 victory over Oman.

"We sent Martin [Boyle] for a scan yesterday and the outcome of that assessment is that he will be out of action for an indefinite period," Socceroos coach Graham Arnold said in a statement.

"Martin was desperate to stay with us but we’ve decided that the best thing for his long-term career for both his club and country is for him to return to Scotland where he can receive great care at Hibernian FC.

"Martin has made a great impact in his time with us and it is unfortunate timing, but his Socceroos journey is not over and we look forward to him pressing for selection for matches later in 2019 and as we go through the process of qualification for the next FIFA World Cup."

The Socceroos will name a replacement for Boyle for the tournament in the coming days.

The likes of Tomi Juric, Adam Taggart and Dimi Petratos are expected to come into consideration.

"The Socceroos have become a big part of my life in a short period of time and I’m gutted that I won’t be able to be with the boys in the UAE at the tournament," Boyle said.

"My focus now will be on my recovery and returning to the pitch as soon as possible with Hibs. Throughout the tournament, the team will have my full support from Scotland."
