The show takes place inside the Capital One Arena in Washington, which is also advertising AJ Styles, Daniel Bryan, The Miz, Jeff Hardy, Samoa Joe and Randy Orton. It remains to be seen if The Undertaker will wrestle in the match, or if he's simply making a short appearance, like he did for the 25th anniversary episode of Raw this past January.
The Deadman last fought at the Greatest Royal Rumble pay-per-view in Jeddah, Saudi Arabia. He defeated Rusev in a Casket match, and was rumored to appear at SummerSlam. But as of now, it sounds unlikely that we'll see 'Taker at the Barclays Center in Brooklyn.
There were strong hints that The Undertaker was done after he lost to Roman Reigns at WrestleMania 33 in Orlando. He broke character by embracing wife Michelle McCool ringside, then proceeded to leave his attire in the middle of the ring.
However, Undertaker came back at WrestleMania 34 and easily defeated John Cena, while showing that he is far from done as an in-ring performer. Fans continue to wonder just how much Undertaker has left in the tank, however, but it would be epic if he were to wrestle in the milestone 1,000th episode of SmackDown.
Undertaker has spent the bulk of his last 20 years on the SmackDown roster, so it'd only be fitting for him to wrestle once again for the blue brand. If he does take part in another match, however, nobody should be surprised if we don't find out until the day of who is opponent would be.
Many consider Undertaker as the greatest wrestler of all-time, but he is 53 years of age and has battled multiple injuries, even requiring hip replacement surgery. His career could be ending sooner rather than later, so fans just have to appreciate whatever else left he has at this point.
