The Royal Rumble 2020 is set to take place on January 26. Over the past few days, participants of the 2020 Men's Royal Rumble match have been making the headlines. With only three spots unannounced in the match, fans are thinking that WWE star John Cena could conceivably show up as a surprise entrant for one of the spots. Why? Blame the wrestler's recent Instagram post for it. Cena posted a picture from 2018 Royal Rumble, which was the last time he appeared in a Royal Rumble match.
