Ray made a bizarre pitch on a recent episode of Busted Open Radio, where he stated that The Rock might show up at the Saturday night event to confront Cena and set up a third WrestleMania match between the two megastars for 2026."For some reason, I don’t think this ends in Washington, D.C. for John. And I would not be shocked if in the midst of all of the happy, happy, joy, joy, [Rock’s theme song] ‘If you smell what The Rock is cooking [plays]. I’ve said this before, it just doesn’t sound right — John Cena, last match, Washington, D.C., Saturday Night’s Main Event. What sounds right is John Cena, last match, WrestleMania, Las Vegas.” It's hard to take Bully Ray's pitch seriously, as Cena is not among those who go back on their word. For now, it's certain SNME would serve as his final goodbye.
