West Ham striker Carlton Cole could be out of action until the end of January.

Cole suffered a knee injury during last week's 5-3 win over Burnley at Upton Park, although he will not need surgery.

Asked about reports Cole would be out until the end of January, manager Gianfranco Zola said: "It might be like that. We don't know exactly, it depends how his knee reacts. We are talking about weeks not months. We will take it day by day."
