Real Madrid are away to Atletico Madrid on Sunday for the Madrid derby.
Vinicius Jr was expected to return for this clash, with initial reports claiming that the Brazilian has recovered quicker than expected.
However, reports now claim that Sunday’s game has been deemed too soon for Vinicius.
After examining the Brazilian, Real Madrid are against risking him in such a big game away from home.
Real do not want to rush Vinicius back, and he is now expected to be eased back into the team on Wednesday when Real Madrid face Las Palmas at the Santiago Bernabeu.
The Brazilian attacker has not played for Real Madrid since they beat Celta Vigo 2-1 on 25th August.
