The Undertaker is widely expected to appear at WrestleMania 35 in East Rutherford next month, but there haven't been a=hny indications yet as to what WWE will do with him.
In fact, WWE doesn't have any plans for The Deadman yet at WrestleMania 35, according to the Wrestling Observer Newsletter (h/t Cageside Seats). This is despite the fact that WrestleMania is less than a month away now, and WWE has to start building up its matches soon.
Interestingly, Felix Upton of Ringside News reported earlier this week that there were talks about having Undertaker face Kurt Angle - with the latter announcing his plans to retire after WrestleMania 35. However, Upton added that Undertaker "doesn’t want to wrestle in this kind of match right now." Thus, we all continue to anxiously await the opponents for each of the two legends.
Upton also recently reported earlier this month that 'Taker hadn't been booked for WrestleMania yet because WWE wasn't sure how they would use him yet. Only seven matches have been announced for the card thus far.
That said, we're still waiting for the announced opponent for Angle's swan song match and Buddy Murphy's Cruiserweight Championship match. WWE seems intent on finalizing many of the matches at the last minute, so we might not even learn who Undertaker's opponent is until the week of WrestleMania - but hopefully sooner.
Undertaker last wrestled at the Crown Jewel pay-per-view in November. There, he and Kane reformed the Brothers of Destruction tag team - but they lost to D-Generation X. This came after 'Taker lost to Triple H at the Super Show-Down in Australia.
What This Means
Given his age (54 this month), and recent injury history, we know The Undertaker isn't far off from retirement. He works an extremely reduced schedule now, and we know the future Hall of Famer can't wrestle long matches anymore. For all we know, this could be his last match at WrestleMania, and perhaps it's why WWE is taking its time in deciding who the opponent should be.
