Aston Villa defender Chris Herd has been ruled out of Australia's World Cup qualifiers against Oman and Thailand this month.
After winning his maiden call-up to the Socceroos squad last week, the 22-year-old was tipped to make his much-anticipated bow for Holger Osieck's side this Friday against Oman in Muscat.
However, an ankle injury picked up near the end of Saturday's 3-2 win over Norwich means the midfielder will now have to wait for his first full international cap.
"I picked up the knock very late in the game and I'll be gutted if I have to miss out," Herd told The World Game.
"The important thing is if I am playing well for my club, then hopefully chances will come for my country.
"I'm still only 22 and I like to think I have a little bit of time on my side."
