Essien out for six months, say Chelsea
Chelsea have confirmed that Michael Essien's latest knee injury will keep him on the sidelines for up to six months.
The Ghana midfielder damaged ligaments in his right knee during a training session last week, the third serious knee blow of his career, and has undergone an operation.
A club statement read: "Following an injury to his right knee in training last week, Michael Essien had surgery today to repair a ruptured anterior cruciate ligament and meniscus. The surgery was successful and Michael's full recovery could take up to six months."
Chelsea manager Andre Villas-Boas added: "Everyone at Chelsea wishes Michael well for his recovery. His team-mates and all the staff and I look forward to helping him return to playing as soon as possible."
The Blues are now expected to move in the market for a new midfielder, with Joao Moutinho of Porto linked with a reunion with Villas-Boas, and a return of Scott Parker to Stamford Bridge also floated.
