Chelsea defender David Luiz faces several weeks on the sidelines.

The Daily Mail says Luiz has added to Chelsea's woes with an injury he fears may rule him out for weeks.

Luiz was on the Liberty Stadium pitch for only 22 minutes as Chelsea went out of the Capital One Cup in the semi-final but he damaged a calf muscle in the final seconds.

Rafa Benitez's squad is already depleted by Eden Hazard's ban for kicking a ball boy and because John Mikel Obi and Victor Moses are at the Africa Cup of Nations.
