#5 His physical condition and exciting possibilities
After his match at WrestleMania 33 against Roman Reigns, the Phenom underwent a hip replacement surgery. It was expected that this surgery would possibly spoil his physical condition and hence, it would be difficult for him to wrestle again.
However, Jerry Lawler, on a podcast in November, said that when he saw The Undertaker, he looked to be in great shape, which, is probably an indication that he is gearing up for a match.

Also, if this is the case, there are quite a few exciting prospects for a match featuring the Deadman at WrestleMania 34, with the hottest of them being a dream match-up against John Cena. Given the current free agent status of John Cena, it would make the most sense if he squares up against the Reaper. It would have been more interesting had the streak not been broken, but still, is a relishing prospect.
Thus, a return to ring seems unlikely at the Royal Rumble, but all eyes would now be on 8th April 2018, when WrestleMania 34 finally unfolds.
