Any last minute changes to the show would have to be made by tonight on Raw and tomorrow night on Smackdown Live because the talent will be flying out on Wednesday.
WWE has yet to officially remove John Cena and Daniel Bryan from advertisements but the last word on Cena is that he is 100% out of the show. If WWE does not address Bryan's status on Tuesday night then we should know more by Wednesday when the wrestlers start to fly out.
As you could imagine, there are several wrestlers that would rather not go to Saudi Arabia. The same applies for much of the production staff.
