With reports stating that Cena was a favourite to face The Undertaker at WrestleMania 32, that could have indeed been 'Taker's final ever match. Rumours of his retirement have circulated for months now, and he couldn't have gone out any bigger than facing John Cena at the biggest 'Mania of all-time. But with Cena's injury, that match is now off. What that could also mean, is that The Undertaker's retirement is also now postponed. If he just waits another year, he can then go out how he envisioned, against the biggest star in the business. Any other opponent he retires against is now just going to feel like a substitute or a letdown. Cena versus Undertaker is the match, but it won't be happening at WrestleMania 32.
