Marca says Thibaut Courtois was injured in training.
Jose Felix reports that the goalkeeper could not finish training today and left Real Madrid training ground in Valdebebas crying.
It is said that Courtois injury occurred in the meniscus of his knee but it was not the same area where he tore his ACL earlier this season.
However Real Madrid are deeply concerned about their reliable goalkeeper as he could be out for the rest of the season.
It will be a big setback for the Belgian who is expected to return to action after the national team break.
