Three days out from Australia's World Cup opener against Turkey there are potential fitness concerns surrounding Mohamed Toure after the striker was absent from Socceroos training.
Toure was the only player of the 26-strong squad not involved in the 15-minute window that media were permitted to watch at Australia's training in Alameda on Wednesday (Thursday AEST).
Coach Tony Popovic and assistant Hayden Foxe were spotted in a discussion with team medical boss Dr Mark Jones ahead of training.
It would be a hammer blow to the Socceroos if dynamic striker Toure is unavailable for any part of the tournament.
The 22-year-old had been expected to lead the line in Saturday's opener against Turkey at BC Place in Vancouver.
If Norwich City sensation Toure is not fit, one-cap striker Tete Yengi, veteran Mathew Leckie and Nestory Irankunda loom as the options to replace him.
