Vinicius who has not played since sustaining the injury during Real's win at Celta Vigo on August 25, missed the start of Brazil's qualifying campaign for the 2026 World Cup.
Real manager Carlo Ancelotti said Vinicius could return for Sunday's derby against Atletico Madrid.
Brazil, who beat both Bolivia and Peru this month, host Venezuela in Cuiaba on October 12 and take on Uruguay in Montevideo five days later.
They are level on six points with world champions Argentina but top the standings on goal difference.
