Ashley Cole could be out for weeks after an implication of his leg injury.

Cole missed three games after picking up the injury against Atletico Madrid last month and required an injection to face Manchester United on Sunday.

"He aggravated the injury before the United match and further injured it during the game," said a spokesman.

It is unclear how long the left-back will be sidelined for, with Chelsea's spokesman describing the injury as a depressed fracture of the tibia.
