WWE legend John Cena has hinted he will retire after WrestleMania 39.

Cena returned to RAW on Monday in front of a deafening home crowd in Boston.

The wrestler-turned-actor fought back tears amid the loud ovation from the fans before holding a “Never Give Up” T-shirt in front of the camera.

The 45-year-old looked back on that beautiful moment after the show as he took to Twitter and revealed that was the first time he felt his career is coming to an end.

Cena tweeted: “Last night was the first time I entered the arena and had the thought that it might be the last time.

“I’ll never be able to put into words how much I love the #WWEUniverse.”

Some fans are already starting to believe Cena is set to hang up his wrestling boots and so they took to the comments’ section to thank him for all the memories he has given them since his debut in 2002.

This WWE supporter tweeted: “When you think like that, it is time to hang it up.”

Another posted: “if this man retires at Mania and I’m not there I’ll never forgive myself. Now I HAVE to go no matter what lol.”

A third wrote: “I’ve watched you since your debut back in 2002. It’s been one helluva ride my dude!!

“Wishing you nothing but the best! Thanks for all the amazing memories!!!”

This fan commented: “Literally I was in tears. Thank you for making my childhood awesome.”

And that one tweeted: “NO DON’T SAY THAT GOAT. STILL LOT LEFT IN THE TANK.”

Cena then had an intense confrontation with US Champion Austin Theory in the ring.

After a brutal exchange on the mic, it was confirmed that the two wrestlers will face off for the title at WrestleMania.

Mania takes place on April 1 and 2 at the SoFi Stadium in Hollywood, California.
