What has happend to the Undertaker?

Answer 1

It was reported a few weeks before Bragging Rights that The Undertaker was suffering from an injured shoulder, when the injury first happened a few months ago and it became apparent that The Undertaker had torn his rotator cuff in the shoulder, WWE planned for the Undertaker to lose a Buried Alive match against Kane at Survivor Series and then rest up his shoulder after the event. When the pain got worse, the call was made to have the Buried Alive match take place at Bragging Rights and get the surgery over with. It has been reported that The Undertaker may not be back in the ring until 2011. It was announced on December 17, 2010, that The Undertaker had begun physical therapy for his shoulder and doctors said they are doing all they can for him to be healthy enough to compete at WrestleMania.
