3: Bray Wyatt
Bray Wyatt has been absent from WWE TV since losing the Tag-Team Titles with Matt Hardy in the middle of August.
The former WWE Champion had fallen into something of a creative rut in the last few years, and as a result, the company has decided to give him some much needed time away from television.
Despite his poor booking, Wyatt still has the potential to be one of the top characters in the WWE, and if recent rumors are to be believed, The Eater of Worlds is set to return with a slightly different gimmick.
One rumor that has persisted in recent months is that Wyatt will reunite with his old Wyatt Family team-mate, Harper in a mini-reunion of the popular stable.
If that is the case, then one of the two men will have to switch brands, and Crown Jewel could present the WWE with the perfect opportunity to re-introduce Bray Wyatt to Tuesday nights.
Having Wyatt and Harper come down and take on AJ Styles would guarantee a big pop on the night, and given Wyatt's previous record, one more big PPV defeat probably won't do him too much damage.
Styles and Wyatt have never had a match with each other on PPV before either, so at least this would provide the WWE Universe with something different.
