Neymar was ruled out for four weeks in mid-October with a hamstring injury he suffered playing for his country in a 1-1 friendly draw against Nigeria.
A day after that October 13 outing in Singapore PSG reported that an MRI scan showed that their star player had suffered "a grade two lesion" in his left hamstring.
Brazil face Argentina on November 15 and South Korea four days later.
In Neymar's place Brazil coach Tite has called on Real Madrid's 18-year-old Rodrygo for the friendlies in Saudi Arabia and Abu Dhabi.
The latest in a catalogue of injuries since joining PSG in 2017 halted a prolific period for Neymar, who had scored four goals in five Ligue 1 games.
