A late decision would be taken on the fitness of defender Isaac Vorsah for Saturday's Group D clash with Australia, says Ghana coach Milovan Rajevac.

Vorsah is carrying an injury and has not been involved in training sessions after Ghana's opening win over Serbia last Saturday in Pretoria.

The Black Stars play Australia at the Royal Bafokeng Stadium in Rustenburg in a group which has been thrown wide open after Serbia beat Germany 1-0 to join Ghana - who play pointless Australia - with three points.

Rajevac does not expect to have Vorsah in his squad for the game against the Socceroos.

"Vorsah has not been training. I dont think he would be able to play," said Rajevac on Friday after Ghana's final training session ahead of the match.

"We would check up on him and make a decision before the game."

However, Rajevac says he has options available if the defender fails to be fit for the game.

"But we have enough players to replace anyone. We cannot force any injured player to play when he's not ready."
