On tonight's special WWE Raw 25, The Undertaker made a special appearance on the broadcast from New York City's Manhattan Center, where a portion of tonight's show will air from.
During his in-ring segment, The Undertaker called the ring inside the Manhattan Center "sacred ground" due to him making his Raw debut on the very first episode back in 1993. He then ran down a small list of people who have fallen to him prior to issuing an ominous statement in which he said "I declare for all of those who have fallen, it is truly time...you REST IN PEACE!"
This statement has led some to begin speculating whether or not The Undertaker will be retiring; however, it should be noted that nothing regarding this has been made official as of yet ever since the initial speculation began at last year's WrestleMania.
As of this writing, it remains unknown whether or not The Undertaker will appear at the Barclays Center in Brooklyn for any remaining portion of Raw 25.
