WWE Saturday Night's Main Event marked the retirement of John Cena, who shockingly tapped out to Gunther in his final match.

John Cena officially retired from professional wrestling this weekend, and had some famous pals sent him congratulatory messages.

In the end, there were no surprises. No run-ins or plot twists. No headline-stealing appearances from The Rock. Instead, WWE played it straight and simple with John Cena's swan song — as it knew it had to do.
