-- The reason for WWE going back-and-forth with the Casket Match at the Greatest Royal Rumble is simply due to "creative plans" changing. There was a rumor that it was because of comments that Rusev made publicly about Undertaker being old but this is apparently not the case at all.
-- Apollo Crews is back to using his full name, likely due to the fact that the original reason for the change - because Vince McMahon didn't want him to be associated with the Parkland, FL shooter Nikolas Cruz - is no longer in the news and thus not an issue.
