The UK Sun is reporting that The Undertaker was spotted this week visiting David H Kock Pavilion Hospital for Special Surgery. U.S. News has ranked that hospital as the best in the country for orthopedics and second for rheumatology.
His reason for being there was not confirmed but it was implied that he was there for his hip surgery. He was holding off on getting hip replacement surgery and the word was that once he opted to get it then his in-ring career would be over. Although WWE has not confirmed this 100%, the belief is that his match with Roman Reigns at WrestleMania was his last.
