#4 The OC ( AJ Styles vs ???)
This one should be a no-brainer. AJ Styles is scheduled to compete against the winner of the pre-show Battle Royale in a match for his US Championship.
While The Phenomenal One certainly doesn't need any help to win a match, his running buddies, Luke Gallows and Karl Anderson will surely get involved in the match and help Styles retain the US Championship regardless of which Superstar earns the opportunity to face him.
#3 Matt Hardy (Seth Rollins vs Bray Wyatt)
Matt Hardy has not been seen on WWE television for quite some time even though the veteran is actively performing at live events. The former ECW Champion has hinted on his social media that he plans to bring back his 'Broken' gimmick when he returns, which he has teased will be soon.
Wyatt and Hardy have had a long history together - as friends as well as foes. Even with The Fiend's current popularity, it is highly doubtful that WWE will hand him the Universal Championship at Crown Jewel, especially because he is a SmackDown Superstar now.
So having Matt Hardy make his return and cost The Fiend his match would not only help Rollins take the Universal Championship back to RAW but would also give the fans a remarkable feud between two of the most Bizzare and unique characters in WWE history - The Fiend and The Broken Matt Hardy.
