The Brazil international was replaced in the early stages of Friday's 1-0 win over Celta Vigo, and there were initially fears that the injury could keep him on the sidelines for an extended period.
However, Ancelotti has suggested that the issue is only minor, and while he is unlikely to feature against Getafe next weekend, the forward should be back for the clash with Real Sociedad on September 16.
«Vinicius had a niggle in the first half and we changed him. We'll see what it is in the next few hours, it looks like some discomfort in the muscle in his leg,» Ancelotti said on Friday night.
«Vini Jr. wanted to continue and I don't think it was too serious. He tried and it was niggling him a little bit, so we made the decision to replace him. I don't think he'll play against Getafe and the break will help him to recover for when we play again.
»He had a good start to the game, he seemed unstoppable. It's a shame. We found it more difficult without him, but also due to the fact that they played very well at the back."
Jude Bellingham continued his excellent start to his Real Madrid career with the only goal of the match against Celta, and the Englishman has now netted four times in three league appearances for Los Blancos.
«Bellingham is doing very well, he keeps scoring and contributing to the team,» said Ancelotti after the match when questioned on the big-money arrival from Borussia Dortmund.
«Goals aren't his biggest quality but he's doing well. He is good off the ball, he's intelligent and his timing is good. He's got a lot of ability on the edge of the area.»
