Why Brazil vs. Argentina World Qualifier Match was halted
Brazil and Argentina's World Cup qualifier match was abandoned just minutes after kick-off on Sunday after Brazilian health officials objected to the participation of three Argentine players they believe broke quarantine rules.

The visiting team walked off the pitch at the Corinthians Arena after the officials came out to stop the game.
The shocking intervention came hours after Brazil's health authorities had said 4 England-based players for Argentina had to quarantine.
Although it did not name the four, the players with English Premier League clubs are Emiliano Buendia and Emiliano Martinez of Aston Villa, and Giovani lo Celso and Cristian Romero of Tottenham Hotspur.
Martinez, Lo Celso, and Romero had all started the game in Sao Paulo.
No date for the rearranged fixture has been set with Argentina players leaving to prepare for their next World Cup qualifier - at home to Bolivia on Friday, 10 September.
Fifa will now gather evidence from all sides to fully understand the events that led to the match suspension before it decides on the most appropriate course of action.
