Napoli are likely to be handed a 3-0 loss by the Italian league's judge for failing to show for their Serie A match at Juventus on Sunday night.
Napoli did not travel to Turin for the game after local health authorities ordered the squad into quarantine after two players - midfielders Piotr Zielinski and Eljif Elmas - tested positive for coronavirus.
It will not be known whether Juve will be awarded a win by default - or if the match has simply been postponed - until next week's disciplinary commission, where Napoli will make their case.
Napoli had requested that the match be postponed and club president Aurelio De Laurentiis had also contacted Juventus asking the same.
"He texted me a couple of days ago, asking me to postpone the match," Juventus president Andrea Agnelli said.
"My answer was that Juventus abides by the regulations."
Vincenzo Spadafora, Italy's sports minister, said he would also speak about the issue with the heads of the Italian soccer federation and the league, in two meetings already scheduled for Monday.
The Italian league's protocol for COVID cases is the same as UEFA rules. If a team has 13 available players, including at least one goalkeeper, the game can go ahead.
The entire Napoli team has been tested constantly after playing Genoa last weekend. More than 20 Genoa players and staff members have tested positive.
Genoa's match at Torino on Saturday was postponed.
Free-scoring Atalanta meanwhile remain top of table ahead of AC Milan on goal difference thanks to a 5-2 victory over Cagliari which takes their tally to 13 in three games.
Luis Muriel gave the Bergamo club the lead after just seven minutes and, although Diego Godin equalised on his Cagliari debut, further goals from Papu Gomez, Mario Pasalic and Duvan Zapata put the hosts 4-1 up at the break.
Joao Pedro reduced the deficit early in the second half but Sam Lammers sealed the match with his first goal for Atalanta with nine minutes remaining.
Three second-half goals were enough for AC Milan to move up into second place courtesy of a 3-0 home win over Spezia, who are playing their first-ever season in Italy's top flight.
Inter Milan dropped their first points of the season as they drew 1-1 against Lazio in a match that saw both teams reduced to 10 men late on in Rome.
Lautaro Martinez fired the visitors into the lead, but Lazio hit back through Sergej Milinkovic-Savic after the break.
Lazio forward Ciro Immobile was sent off 20 minutes from time for hitting Inter midfielder Arturo Vidal, while Inter midfielder Stefano Sensi was also shown a straight red card for a similar incident with Lazio defender Patric with three minutes remaining.
Elsewhere, Parma picked up their first points of the season with a 1-0 win over Hellas Verona, while Benevento beat Bologna by the same scoreline.
