According to PWInsider the match between Seth Rollins and Brock Lesnar for the WWE Unisersal Championship at Wrestlemania 35, was not supposed to start the show. The match was moved in opener barely 1h30 before the start of the kickoff.
Still according to PWInsider, the match for the red belt was supposed to take place before the Main Event “Winner Take All” between Ronda Rousey, Charlotte Flair and Becky Lynch. The final decision was made around 3:30 pm local time, during the opening of the doors at MetLife Stadium.
Hulk Hogan, then present on the stage with Alexa Bliss opening the show, had no idea why Paul Heyman made his entry and headed for the ring. This decision was made after Hogan was informed of his segment with Alexa Bliss. Many employees were also surprised by this change and many were not aware of it.
Regarding the original plans, AJ Styles and Randy Orton were supposed to start the show in the opening match. However, the rest of the map did not move and remained as it was originally built by officials.
We can not confirm why this change was made but the most likely reason, according to PWInsider, is that it was made to allow Brock Lesnar to return home as soon as his match was over, without specifying why it was necessary. .
