Speculation on the returning “former WWE Champion”
According to Fightful Select, there was no name given as to who the person returning on Raw: “Day 1” on Monday is, but the source they spoke to said that this person is not currently on the active WWE roster.
The source also specifically used the words “former WWE Champion” when describing this person.
The wording does not specifically identify which championship or if the person is male or a female.
So that narrows it down…not at all. Some “speculation.”
