David Luiz has a knee injury and did not travel to Switzerland for Chelsea's Champions League Group E clash at Basel.
The Brazil defender, who scored the winner in April's Europa League semi-final first leg against the same opposition, has a bruised patella and will be out for around one week, the Blues announced on their website.
