WWE issues a text out that has announced:

"Sheamus has suffered a torn labrum in his left shoulder and will require surgery, scheduled for next week. As a result, The Celtic Warrior is expected to be sidelined for four to six months, WWE.com has learned."

WWE.com have now added more details in regards to how the injury was suffered on the recent South Africa tour.

 Sheamus’ leg started to heal, but he discovered his range of motion limited in his shoulder and he experienced sharp pains radiating down his arm, he said. During a pre-Raw workout, Sheamus felt another sharp pain in his shoulder and notified WWE medical staff.

“We performed a specialized MRI with a dye inserted to highlight the structures within the shoulder joint," said WWE ringside physician Dr. Chris Amann. "Doctor Samson and I both reviewed the film, and it appears that Sheamus has a cartilage [SLAP] tear.”

As a result, Sheamus will undergo arthroscopic surgery next week to fix the tear, which doctors hope will offer him the best chance of recovery and the best outlook for a normally functioning shoulder.
