Socceroos coach Pim Verbeek said on Friday the field at the Ruimsig stadium, near Johannesburg, had deteriorated over the past year.
"We are thinking, of course, about plan B and plan C but let's see first tomorrow how it looks," he told reporters ahead of a warmup match against the United States to be played at the ground.
"When I was here last year it was fantastic already so I don't know what has happened," he said. "On the other hand it is just 10 days...I'm not so sure we will destroy the pitch in 10 days but if that's the case I think we will have to find another place."
Midfielder Brett Emerton will miss Saturday's friendly due to injury worries but is expected to be back in full training next week while Harry Kewell will be on the bench and may play after a long recovery from a groin strain.
"I am not concerned at all, I am just taking no risk for the player (Emerton). He is too important for us, we have three tough games in qualification so I want him fit next week," he said.
