People may joke about him being invisible, but WWE fans really haven't been able to see John Cena recently.

It seems like the Cena Era is well and truly over, with the 16-time world champion's last Monday Night Raw appearance coming in January.

Of course he appeared at WrestleMania 35 to confront Elias as his 'Doctor of Thuganomics' persona, but it was nothing more than a flying visit.

His schedule is about to become even more packed as he's been confirmed to star in the latest instalment of the Fast & Furious franchise, which is currently in pre-production.

So that doesn't leave much time for a return to the ring anytime soon, and judging off some recent quotes he gave to The Wrap, there's a slight chance he may never come back.

That's a long shot - Cena loves wrestling and WWE is his home - but he admitted last month that the company 'doesn't need him anymore'.

But in a lengthy explanation Cena can't be 100 per cent sure he will return.

“I’ve made it a promise never to shortchange the WWE consumer,” Cena told The Wrap. “They are dedicated, they demand excellence and if I can’t keep up with the speed of the show then I’d coach at the Performance Center.

"I am not saying ‘I’m doing this and leaving you guys behind.’ I’m having a talk with the man in the mirror and saying I might be a step slower and I am not sure it is right for me to go on.

"You always want to walk away at the right time and never want the courtesy clap from the audience.

"I don’t want to go out there and think I can perform like I’m 30, because I can’t.

“It’s something I’ve seen a few instances of and I’m going to try everything in my power not to do that.”

“I am not sick of it, I am just trying to have that realistic conversation that not many people in sports or entertainment - or sports entertainment - have, they want to hold on to that flame as long as they can.

“I would much rather leave a lasting impression for what I did then try to milk the system for selfish gain.”

From his words, it doesn't look as though Cena is longing to step between the ropes anytime soon.

It looks as though he's comfortable in trying to advance his career outside the ring, and who can blame him?

He's exerted a lot of pain on his body over the last 17 years and he deserves his chance to make a name for himself on the big screen.
