Chelsea striker Salomon Kalou will be sidelined for almost two weeks after suffering a minor tear to his upper left thigh on Wednesday. The 24-year-old sustained the injury in the Blues' loss in the League Cup to Blackburn Rovers at Ewood Park on penalties. The Ivorian ace scored once in the quarter final match to take his tally to four goals this season. Now Kalou will miss Chelsea's upcoming matches against Manchester City, Apeol Nicosia and Everton. He also may not feature against Portsmouth on 16th December.
