According to WONL and SI, The Undertaker is officially out of Wrestlemania 34.

Thank God. I truly hope he never goes near a ring again...not because I don't like him, but because I DO like him and he absolutely embarrassed himself last year. I don't want people's last images being that of someone so deteriorated. Had I known they did never use the streak to get someone over id have wished he walked away after the sseries with triple H.
