Cena says he's thought about retiring from WWE

John Cena is thinking about when his time in WWE will come to an end.

Responding to a question from TMZ Sports about whether The Undertaker and Bill Goldberg should retire following their match at Super Showdown in Saudia Arabia, Cena said he's been evaluating his own WWE future recently.

"I think an individual's career is up to the individual. I think that's pretty much the way I can describe that," he said. "I've been having the same conversation with myself and I'm only 42. It's something we got to address each day and that's individually specific. When those people are ready to stop, they'll stop."

Cena has appeared sporadically on WWE programming in recent years while focusing more on his Hollywood career. He's currently hosting "Are You Smarter Than a 5th Grader" on Nickelodeon, and will be starring alongside Vin Diesel in the upcoming movie "Fast and Furious 9."
