BARCELONA, Spain -- Barcelona says Rafael Marquez appears to have become the club's third player to get swine flu.

Fellow defender Eric Abidal and midfielder Yaya Toure have already been sidelined with the viral illness.

Barcelona said Saturday that Marquez "displayed viral symptoms, with general discomfort and fever." It expects to confirm later Saturday whether the symptoms were caused by swine flu.

All three players will miss Saturday's Spanish League game against Athletic Bilbao and could be out for Tuesday's clash against Inter Milan in the Champions League as well as the traditional Spanish "clasico" against Real Madrid the following weekend.
