The World Cup qualifier between Brazil and Argentina was interrupted on Sunday.
Shortly before kick-off, the Brazilian health authority ordered a quarantine for four Argentine Premier League players.
But three of them were on the field when the whistle kicked off.
After almost ten minutes of play, the game was then interrupted, apparently, officials of the health authorities and police officers had caused the Argentine team to disappear completely into the dressing rooms.
It is now unclear whether and how it will continue.
The Brazilian health authority (Anvisa) ordered Emiliano Martínez and Emiliano Buendía from Aston Villa as well as Giovanni Lo Celso and Cristian Romero (both Tottenham Hotspur) to quarantine on Sunday before the classic between the South American football powers in São Paulo.
However, Martinez, Romero and Lo Celso were then starting XI.
Only Buendia was missing from the list.
"Anvisa considers the situation to be a serious health risk and has therefore advised the local health authorities to immediately quarantine players who are prohibited from participating in any activities," said a statement from the authority.
In addition, the players should no longer be allowed to stay on Brazilian territory.
Brazilian corona rules
Martínez, Buendía, Lo Celso and Romero had come to Brazil with the Argentine national team from Caracas. Upon entry, the England professionals did not state, according to the Anvisa, that they had been in the United Kingdom, Northern Ireland, South Africa or India in the past 14 days. Foreign travelers who were there during this period are not allowed to enter Brazil due to the corona restrictions.
The English Premier League clubs had previously refused to transfer players to countries on the British government's so-called Red Corona list, many of them in South America and Africa. Argentina assumed they could count on their England professionals in the three World Cup qualifiers in South America. Aston Villa, for example, had announced that Martínez and Buendía could only play the first two instead of the three games.
