Vinicius Junior was substituted in the 27th minute of the game against Colombia and Brazil with some discomfort.
The medical staff had to put a hard ice pack on his thigh.
After the match the Real Madrid winger was seen walking out of the locker room.
I knocked on the door and felt a little pain later I thought it was the same injury I had had before but tomorrow we will test and see Vinicius told the media.
It will be difficult for me to play against Argentina but I will try my best I am ready.
The last time Vinicius suffered a hamstring injury he missed a full month.
We hope the tests do not find any serious injuries Los Blancos have enough of them.
