Cahill's fate will be decided by FIFA's disciplinary committee
either on Wednesday or Thursday (South African time), with his one-match ban likely to be confirmed.
The committee does have
the option to increase the ban to two games if it decides the 56th minute challenge on Germany midfielder Bastian
Schweinsteiger was of a serious enough nature.
That is understood to be highly unlikely, with a one-match ban
only set to rule Cahill out of the Socceroos' clash with Ghana in
Rustenberg and freeing him for the final Group D game
against Serbia in Nelspruit.
Also a concern is that three Australians - captain Lucas Neill,
defender Craig Moore and midfielder Carl Valeri - will carry yellow
cards in to the game against Ghana.
