The original booking plan for the WWE Fastlane main event called for Bray Wyatt to interfere and cost Brock Lesnar the match, setting up a WrestleMania showdown between Lesnar and Wyatt. That scenario was scrapped because Vince McMahon has settled on a new WrestleMania opponent for Brock Lesnar.
According to Dave Meltzer of F4wonline.com:
"The reason Wyatts didn't interfere in the [Fastlane] main event is because Brock's WrestleMania opponent has been changed to Dean Ambrose."
