Cagliari has been given permission to open its new stadium to fans, three days after its home game against Roma was called off.
Italy's National Observatory on Sports Events gave the green light on Wednesday after an earlier inspection.
Roma was awarded a 3-0 victory in its game at Cagliari, which was postponed last weekend for safety reasons after the Sardinian club defied orders to play the Serie A match in an empty stadium.
Cagliari's new Is Arenas had yet to pass security tests, and local authorities had ruled that the match would take place without fans present.
Cagliari president Massimo Cellino urged fans to ignore the authorities, posting a statement on the club website calling for fans to attend peacefully, regardless of the ruling. Cellino suspended himself on Tuesday.
