UPDATE: Gareth Bale set to miss El Clásico

Things weren't looking good for Bale this morning when reports said that he was still questionable for Saturday's match against FC Barcelona. But it is all worse now, as Real Madrid confirmed on their official website that Bale has an injury in his piriformis muscle -- glutear region --.

After the tests, Gareth Bale has been diagnosed with a muscle injury in his piriformis muscle. He stays pending of clinical evolution.

Considering that players need to be cautious with this kind of injuries, Bale will almost certainly miss Real Madrid's next two games -- Liverpool and Barcelona -- and could be out for 15 days.
