Michael Essien will be out of action until Christmas at the earliest after suffering a cruciate knee ligament injury in training.
While the club are not revealing details of the setback for the midfielder, Chelsea-Mad believe the injury is so serious, that it could be career-threatening.
Essien has a history of injuries in recent seasons and this major one could prove to be the final straw for the midfielder Chelsea fans call the Bison.
Good luck, Michael.
