It is said that there were several people who were displeased backstage about the decision to have Undertaker lose to Brock Lesnar at WrestleMania 30, but were not able (and won't) say anything publicly about it.
- The decision to end the streak was reportedly made by Vince McMahon, not Undertaker.
- Regarding who knew ahead of time that the Streak was ending, it is certain that Vince McMahon, Brock Lesnar, Undertaker and Paul Heyman knew, and possibly Triple H and Stephanie McMahon. Beyond that, it is difficult to say. No finish was listed on the script but that isn't unusual and it wasn't the only one for the PPV. None of the agents reportedly knew.
- Those who saw Undertaker backstage at Raw said that he had a heavy limp and looked to be "in rough shape."
The referee in the Brock Lesnar vs. Undertaker match didn't know the end result. The Wrestling Observer Newsletter reports that Chad Patton was actually informed ahead of the match that Undertaker would win, but complied with the rule given to all WWE referees. That rules is that if a wrestler does not kick out, you go ahead and finish with the three count as if it were exactly what was planned.
