Chelsea boss Jose Mourinho has revealed that England captain John Terry may require surgery on his back injury.
Terry injured his back in training earlier this month
The defender has been sidelined for the last four matches but had been expected to return within the next fortnight.
Mourinho was less optimistic and said: "The medical department have said surgery might be a possibility.
"I want them to make a quick decision. I don't know how long John Terry will be out for - three days, three weeks or three months, I don't know."
