There are reports that Cagliari-Milan might be behind closed doors or called off after the local authorities staged an emergency counter-appeal.
The game is due to kick off at 14.00 GMT on Sunday at the Is Arenas, as it had been moved to the Stadio Olimpico in Turin due to fears over public safety and then returned to the original venue by an emergency ruling of the TAR Tribunal on Friday.
However, according to the latest reports, the local authorities who ordered the closure in the first place are staging their own emergency appeal.
The Prefect maintains public safety cannot be guaranteed at the Is Arenas in its current state.
It is now possible the game could be played behind closed doors or even abandoned completely.
