Madrid - Barcelona left-back Eric Abidal is suffering from swine flu and will be out of action for at least a week, the European champions said Friday.

Barca have also revealed that midfielder Yaya Toure has the same symptoms - stomach virus and a high fever - and might also have swine flu.

Both players will miss Saturday's league game away to Athletic Bilbao, and are doubtful for Tuesday's crucial Champions League clash at home to Inter Milan - and also for "El Clasico" against Real Madrid on November 29.

Zlatan Ibrahimovic is also doubtful for the Inter and Real matches, because of a pulled muscle in his left thigh.

Barca are one point ahead of second-placed Real, who are at home to Racing Santander on Saturday. (dpa)
