Argentine captain Lionel Messi has said he is disappointed with the Brazilian health authorities' decision to postpone Sunday's World Cup qualifiers after the match begins.
Just five minutes after kickoff at So Paulo's Corinthians Arena, health officials entered the pitch to announce that play would not continue due to a breach of the country's quarantine protocol by four of Argentina's Premier League-based players.
"Listen to me, we've been here [in Brazil] for three days," Messi said on the pitch, accompanied by his comments on television. "Were they here waiting for the game to start? Why didn't they warn us earlier?"
Brazil's health regulator, Envisa, claimed that Argentine internationals Emiliano Martinez, Cristian Romero, Giovanni Lo Celso and Emiliano Bendia violated health protocols twice.
The Argentine starting lineup included Lo Celso, Romero and MartÃnez. Under Brazilian rules, visitors from the UK entering the country must quarantine for 14 days upon arrival.
In a statement, Anvisa accused players of providing "false" information about their health forms and considered their presence in Brazil "a serious health risk" and advised those players to be in immediate quarantine.
The Brazilian Football Confederation (CBF) was "absolutely shocked" by Sunday's events and said in a statement that Avinsa could have acted "days before" and not after games had resumed.
"The CBF reiterates its disappointment with the event and awaits the decision of CONMEBOL and FIFA regarding the game," it said in a statement.
Avinsa director Antonio Barra Torres claimed the players in question were informed before the game that they would have to self-isolate and did not.
"He had to isolate at the hotel until he returned to his country, but instead went to the stadium to play games," he said. "We informed the players that they have to follow these rules. They didn't."
Argentine Football Association (AFA) president Claudio Tapia, whose team returned to Buenos Aires in the early hours of Monday, said his players followed all health protocols set by CONMEBOL.
He said in a tweet on Sunday: "As AFA President, I am deeply sorry for the suspension of a party to South American football.
"We have always been guided by the current CONMEBOL health law. We await the resolution of the Disciplinary Court of FIFA."
He said: "Four guys interrupted the game for something we don't understand.
“There is a health law through which all tournaments are played, in which the officials of each country approve a protocol that is enforced and signed by the 10 federations, and which we follow to the extreme. What happened is for football. Unfortunate, a very bad image for the world."
CONMEBOL said in a statement that it would be FIFA's disciplinary committee to decide what would happen next.
Brazil is six points ahead of second-placed Argentina in the South American qualifying group for Qatar 2022. Brazil will play next when they host Peru on Thursday, while Argentina will welcome Bolivia on Friday.
