Ghana midfielder Michael Essien is set for another lengthy spell on the sidelines after suffering a fresh injury at Panathainaikos.

The 32-year-old was reported to be making steady progress in his recovery but it appears he has suffered a relapse.

According to Greek portal sports 24, the Ghana international underwent surgery and observation at the Metropolitan hospital this week after suffering a fresh injury at training.

According to the reports, even though officials of the Greek giants are in self-denial, Essien has been diagnosed with bruising of second grade and will be sidelined until at least December.

The career of the famous Ghanaian midfielder has been rocked by persistent injuries amid fears he may not return to his best again.

Essien has endured more injury hell since joining the Greek giants from AC Milan as he is yet to play in a competitive game.

The former Chelsea midfielder has serious fitness concerns with no clear signs of recovery in sight.

The comeback trail of the former Chelsea star appears to be clouded as he struggles to shake off knee and groin problems.

Essien has notoriously been cursed by injuries over the years with no end in sight to the troubles that has affected his form and stature in world football.
