The last time is now for John Cena, who competes in his last pro wrestling match at the latest edition of Saturday Night’s Main Event.

On TV this Saturday: Josh O'Connor makes his "SNL" debut, John Cena competes in his final WWE match, and Erika Kirk sits down for a CBS News town hall.

WWE have spent several days posting clips of Cena’s history with The Rock, resurfacing WrestleMania highlights and old promos as if rewinding one of the defining rivalries in company history.
