Argentine stars Emiliano Buendia, Emiliano Martinez, Giovani Lo Celso and Cristian Romero apparently breached quarantine rules after arriving into Brazil for the fixture having been in England in the past two weeks.
Three of the quartet were named in the Argentine starting XI which took to the pitch in Sao Paulo for Sunday’s game with Brazil.
Amid bizarre scenes around five minutes after the match kicked off, health officials were seen entering the pitch as the action was stopped.
Led by skipper Lionel Messi, Argentina then took to the dressing room.
Dressed in a bib, Messi later emerged in discussion with Brazilian former Barcelona teammate Dani Alves and numerous officials as confusion reigned over whether the match would continue.
But after Messi walked off again, it appeared the match was in danger of not going ahead despite the Brazil team remaining on the pitch in full kit.
As the Brazilians continued to conduct an impromptu training session among themselves, it was reported that the match was set to be called off.
