Celtic star Aaron Mooy has been ruled out of the Australia squad through injury.
The midfielder missed the weekend's game against Hibs, which finished 3-1 to Ange Postecoglou's men.
The 31-year-old has been a key figure for the Scottish champions in recent months.
However, he's been struggling with muscle issues for the last couple of weeks.
The ex-Huddersfield and Brighton player has six goal contributions in his last five matches for Celtic, highlighting his impressive impact on the team.
So, it is both a blow to him and Australia that he won't be able to feature in their upcoming international fixtures due to injury.
Mooy will miss their friendly double-header against Ecuador.
St Mirren's Ryan Strain will now have the chance to prove himself to head coach Graham Arnold having been called up in Mooy's place.
The Buddies right-back has been called up to the Aussie national team setup twice in the past.
He made his international debut against New Zealand in September last year.
Speaking on Mooy's setback, Australia boss Arnold revealed that his injury isn't serious.
He said: “It’s unfortunate for Aaron that he misses these games, something I know he was very much looking forward to playing, but his absence provides an opportunity to a further emerging player as we start this new campaign.
“After speaking with Aaron, who missed this weekend’s game, he would only be able to play limited minutes if he came to Australia, so the decision was made for him to stay in Scotland and continue his recovery."
