According to several sources from within WWE, the plan for the Cena vs. Fiend match at WrestleMania is it’s going to take place in an empty warehouse somewhere in the Orlando area.
The idea is going to be similar to that of the 2017 House of Horrors match between Randy Orton and Bray Wyatt. The exact location is being kept tight-lipped as they do not want fans showing up.
Vince and others within the company want to bring in props to set up around an empty warehouse that will be used to interact with during the match. The other part is that the match is still scheduled to finish at the WWE Performance Center.
Hopefully, the editing job on this isn’t as bad as the Orton vs. Wyatt match!
