John Cena plans to be at many more WrestleMania events.

On Nov. 6, Randy Orton took to Instagram to issue a challenge to his longtime rival John Cena for WWE WrestleMania 36. Orton posted a photo of Cena on the cover of a magazine with the headline "Up For A Challenge." As a caption to the photo, Orton wrote, "I’m on a flight to London and see this striking young man asking me a question. Why yes @johncena I am up for a challenge, are you? Let’s say ohhhh I dunno, #Wrestlemania36 maybe? Or does Hollywood have you booked solid? #WM36"

Speaking to Sports Illustrated, Cena responded to the challenge.

“I wasn’t even aware of that,” said Cena. “I never make the matches, I’m just grateful to be able to perform in WWE. Every day away from it, I miss it more and more and more. I’m becoming more honest with myself about how much I miss it. I’m very eager to get back into a WWE ring soon. And on the subject of WrestleMania, I can tell you this—I haven’t missed a WrestleMania since my first appearance at WrestleMania 19, and I do not plan to miss a WrestleMania for decades to come.”

Cena has not wrestled since the Jan. 14 episode of WWE Raw. He did make an appearance at WrestleMania 35, returning as the Doctor of Thuganomics to confront Elias.

While it is unknown when Cena will return to a WWE ring, he remains busy with his Hollywood commitments. His latest movie "Playing With Fire" hit theaters on Nov. 8 and Cena has been making large donations to the veterans' foundation and Los Angeles Fire Department and California Fire Foundation.
