Mohamed Toure has sent a scare through the Socceroos camp, with the gun striker absent from training three days out from Australia's World Cup opener against Turkey.
But the Socceroos say they expect Toure to return to training on Thursday (Friday AEST), though no specific reason was provided for his absence.
The striker, who has been widely expected to lead the line in Saturday's game at BC Place in Vancouver, wasn't involved in the 15-minute window of training media were permitted to watch on Wednesday.
Toure was the only player of the 26-strong squad not involved, while coach Tony Popovic and assistant Hayden Foxe were also spotted in discussion with team medical boss Mark Jones.
It would be a hammer-blow to the Socceroos if dynamic striker Toure is unavailable for any part of the tournament, given his importance to Australia's attack.
