Like he does every year, Undertaker made his way back to WWE a few weeks ago to set up for a match at the biggest show of the year. He followed through on that, wrestling and defeating Shane McMahon in a Hell in a Cell match at WrestleMania 32 last night (Sun., April 3, 2016) at AT&T Stadium in Arlington, Texas.
It may have been his last match.
This talk seems to come around every year, and it's back again this year. The Wrestling Observer is reporting Undertaker was telling people this was his "final match" and that may be why he left his gloves in the ring before heading to the back. PW Insider reported something similar, stating he had a lot of family there and it was being openly speculated about backstage.
It's worth noting that Undertaker has been advertised for dates on the company's annual tour of Europe later this month.
