The Undertaker revealed he was driving back from the ‘Boneyard’ match to the WWE performance centre when he got a call from a family member.

“It was probably the last time they rang me before I went to the mailbox several times, so I took the call and said, ‘Hi, what’s going on?’ She says, ‘My dad,’ my brother Tim, ‘My dad had a heart attack’,” The Undertaker said.

“I was like oh wow, ok. What hospital were you sent to? Live outside Austin.”

But his niece revealed Tim, his brother and her father, died of a heart attack aged 63.

“I asked her again, which hospital they sent him to and she said ‘no, Uncle Mark left, he didn’t make it,’” he said.

“It was in the middle of everything that was happening, WrestleMania, when everything is perfect, it is hectic and stressful, but now I have to call all my brothers and let them know and then call my mother.”

The Undertaker revealed the situation became harder because he was filming the ‘Boneyard’ match, which involved burying his opponent.

"It was hard to go to the next day with the loss of my brother just as fresh as it could be, and then you know you're in a Boneyard match and everything is centered around buried and it's like man, it makes it tough,” he added.
