According to our source, the horse was a 'Clydesdale'. Wikipedia says "The Clydesdale is a breed of draft horse derived from the farm horses of Clydesdale, Scotland, and named after that region." Our source says Triple H couldn't guide the massive animal away from the trap door, which had a casket (this would hold The Undertaker). That would then rise to the top of the stage during the entrances. According to the source, the horse fell through the stage with Triple H riding it and crushed the casket during the rehearsal. 'Taker was not inside at the time.
The arena was immediately cleared of staff members and rehearsal was canceled. We've been told that the horse was stuck for hours and almost had to be euthanized due to the extreme stress it had suffered. WWE crew members also had to dismantle the stage so the horse could be freed.
WWE management then made the call that it was not worth the risk and plans were scrapped.
