The Spanish centerback will miss the game, as the club confirmed via Twitter. He tried to be ready for the match against Real Madrid after his injury, but Tito Vilanova decided that it was still too soon for him.
That means Barcelona's centerbacks will be Alex Song and Javier Mascherano. Both are defensive midfielders that will have the role of being Barcelona's last men before Real Madrid is able to face Víctor Valdés.
This is something Real Madrid should build on to try to steal the win away from the Camp Nou.
