Jose Bosingwa has been ruled out of action for up to three months.

The Portugual and Chelsea defender has been struggling with a knee problem all season, and he has undergone surgery.

He has not played since mid-October and this week travelled to Lisbon to consult a specialist.

And Chelsea have now confirmed that he underwent surgery, which will rule him out until February.

A statement from the club read: “Chelsea Football Club can confirm that Jose Bosingwa underwent arthroscopic surgery on his left knee.

“His recovery time will be approximately three months.”

However there was some better news from the club as they confirmed that Ashley Cole’s fracture of the tibia does not require surgery.
