Champions Trophy, Group B qualification scenarios: How Australia vs South Africa washout changes things

The Proteas could still qualify even with a loss to England, provided England doesn't win both their remaining matches (against Afghanistan and South Africa).
Australia's path to qualification remains in their control. A victory against Afghanistan in their final game would guarantee their semi-final berth. However, if they lose to Afghanistan, they would need South Africa to defeat England to progress.

England face a must-win situation after their demoralising loss to Australia in the opener. They need victories in both remaining matches to have any chance of qualifying.
The crucial match between England and Afghanistan on Wednesday will determine the fate of all four teams in the group. If both Australia and South Africa lose their final group matches, the winner of England versus Afghanistan will advance to the semi-finals.

Afghanistan currently sit at the bottom of Group B following their comprehensive loss to South Africa. They must defeat both England and Australia in their remaining matches to have any chance of qualifying.
