Chelsea fullback Abdul Baba Rahman is out for the season.
Rahman, on-loan with Schalke, is reportedly set to miss the rest of the season after suffering a serious injury playing for Ghana, says the Daily Star.
Rahman suffered the injury during the African Cup of Nations in Gabon last week.
He was stretchered off during the 1-0 win over Uganda.
According to GhanaSoccerNet, he looks to be out for at least six months.
