#1 WWE booked the match between Rey Mysterio and Brock Lesnar to protect The Fiend
Survivor Series is traditionally known as the battle of two brands to prove brand supremacy, but three brands will be part of the pay-per-view this year. With the addition of NXT, the champions of the Black & Yellow brand will compete at Survivor Series. Moreover, the WWE Champion and the Universal Champion will not clash at Survivor Series, which is the conventional way of deciding the dominant world champion.
As announced on Monday Night RAW, Rey Mysterio will challenge the WWE Champion Brock Lesnar. As a result, the WWE Champion Brock Lesnar will not clash with the Universal Champion 'The Fiend' Bray Wyatt, meaning the latter will find a new opponent at Survivor Series.
It is clear that the company has taken the step to protect both Brock Lesnar and The Fiend. With two thumping victories over Kofi Kingston and Cain Velasquez, Lesnar has the momentum and he can't afford to lose to The Fiend, considering The Beast already suffered two losses this year, which is unusual for him. The Fiend has been indomitable in WWE, and he can't afford to suffer a defeat either, especially after an emphatic victory at Crown Jewel.
