Eight matches have been already advertised for the show including six Championship bouts. But even then, there are a lot of major stars who are to be announced to be on the show.
Superstars like Finn Balor, Nakamura and Asuka are facing the prospect of potentially missing the show if the WWE doesn't manage to spots for them on the card quickly.
So let us take a look at three matches that might still be added to the Hell in a Cell card.
Over the past several weeks, Nakamura has been used as a pawn in the feud between Randy Orton and Jeff Hardy.
And while Orton and Hardy will meet inside the Hell in a Cell structure on Sunday, Nakamura finds himself without an opponent despite being the current United States Champion.
The WWE could solve this problem by having Nakamura host his own US Title Open Challenge. Such a segment could slide in seamlessly in between two matches on the main card.
Nakamura's opponent should be former Tag Team Champion, Luke Harper. Since Rowan's injury, Harper has been off television without a partner to work with. But he remains one of WWE's most talented in-ring workers and could put on a terrific match with Nakamura if given the chance.
It would also help get Nakamura on the show and if everything goes to plan, the Nakamura US Title Open Challenge might even hit it off with the WWE Universe.
