#4 Kane

WWE removed Kane from the Greatest Royal Rumble a couple of days ago. He was initially scheduled as an entrant in the Royal Rumble match but was abruptly excluded from the card.
WWE is yet to provide a reason for his exclusion from the event. A probable reason that Kane pulled out from the show might be his current run for a Republican nomination in Tennessee as the Mayor of Knox County, whose primary race will take place on May 1st.
