John Cena versus The Undertaker was meant to be a main event at WrestleMania 32, but alas it was robbed by Cena's shoulder injury. It had been thought that it could have been 'Taker's last match, but he's now booked on WWE's April European tour, and is almost certainly going to be featuring at 'Mania 33. That decision to stay active is likely based on the idea that he wants to go out against John Cena on the grandest stage. They'll do it at WrestleMania 33, the biggest star now versus the biggest star of all-time. It will be match for the ages, most likely the show-closing main event ahead of Reigns and Lesnar. Cena will go over, The Deadman will retire, and then he'll headline the Hall Of Fame class of 2018.
