John Cena's days in the WWE ring could be numbered ... with the superstar admitting he's been recently giving serious thought about hanging up his trunks for good.
The WWE legend was out in New York when he was asked by Adam Glyn about the disastrous match between and at Super Showdown on Friday in Saudi Arabia.
Goldberg suffered a nasty head wound during the match -- and both wrestlers are being criticized for a sloppy and dangerous performance. Some are calling for both wrestlers to retire.
Cena says when it comes to calling it a career, it's up to the individual and it's not his place to advise either wrestler.
