Barcelona: Barcelona says Dutch midfielder Ibrahim Afellay will be sidelined for four months after undergoing surgery on his right leg.
The Spanish club says Afellay had surgery on Thursday to treat a "chronic injury related to the muscle and tendon" in his right thigh.
The 27-year-old Afellay has suffered a series of injuries since joining Barcelona in 2010. He had surgery to repair a torn ligament in his left knee in October 2011.
Afellay played on loan for Schalke last season and was injured at the German team as well. He is back with Barcelona but has not been playing with the team.
