Barcelona midfielder Xavi Hernandez will miss tomorrow's match with Real Madrid and potentially the last 16 Champions League clash with Milan.
The 33-year-old pulled a hamstring today and, according to the club's official website, will be missing for between 10 and 15 days.
The World Cup-winner will definitely be sidelined for Saturday's Clasico, as well as the match next weekend against Deportivo.
However, it will be a race against time for the veteran Blaugrana man to see if he will be fit enough for the European tie.
