Napoli failed to turn up for their Serie A clash against Juventus on Sunday after a coronavirus row involving both clubs and health and football authorities.
Gennaro Gattuso’s side was not present at Juve’s Allianz Stadium for the game’s kick-off.
They were in isolation on the instructions of the regional health authorities of the Campania region which hosts the city of Naples after midfielders Eljif Elmas and Piotr Zielinski both tested positive during the week.
Napoli, who had won both their Serie A matches so far this season, risk forfeiting the game 3-0.
Club president Aurelio De Laurentiis, who recovered from coronavirus last month, said he believes it is “too dangerous” to travel to Turin, and asked on Sunday evening that the match be postponed “without further delay”.
Serie A insisted that all the health protocols were in place for the match to safely go ahead as scheduled in Turin.
Napoli are the first team in Europe’s five major leagues not to take to the pitch due to the coronavirus pandemic in a game which had remained scheduled.
Juventus players arrived at the stadium about an hour before kick-off.
