UPDATE: In what could be taken as a sign of a possible Fast Lane spoiler, as of this week the people in charge of handling the actual promotional materials for WrestleMania 31 were still under the impression that Brock Lesnar vs. Roman Reigns will be the main event of the show. In the promotional materials, the workers were told to feature Reigns the most prominently, followed by Lesnar and John Cena.
It’s worth noting that WWE has not included Sting in any of the promotional materials for WrestleMania as of yet, and since he’s all but confirmed for the event, his involvement will likely be a major selling point for the show, so new materials will likely be released in the near future to include him.
ORIGINAL: As seen on Monday’s RAW, Daniel Bryan vs. Roman Reigns is now set as the main event for the February 22nd WWE Fast Lane pay-per-view, with the winner going on to face Brock Lesnar for the WWE World Heavyweight Championship at WrestleMania 31.
Prior to the Royal Rumble backlash, the original plans for Fast Lane was to have Reigns defeat a top heel, possibly Big Show, in the main event on the show, while Bryan was likely to lose to Bray Wyatt in order to keep Wyatt strong for The Undertaker.
Regarding booking for Bryan, WWE originally wanted to put him in a match with Sheamus at WrestleMania 31, however Bryan himself requested that he work with Dolph Ziggler instead. It’s worth noting that it’s considered possible that Bryan still ends up working with Sheamus, although it is considered unlikely at this point.
