WWE may have cancelled their plans for The Undertaker vs. Braun Strowman at WrestleMania 32 due to fan backlash. Vince McMahon was reportedly a big fan of the match and was interested in building up Strowman. However, the huge negative reaction from fans online in the first 24 hours after the story leaked was noticed by the company, which may pulled the plug within those same 24 hours. However, McMahon is always changing plans and the match could end up happening anyway.
Meanwhile, WWE also has back up plans for Undertaker. While those plans aren’t known to anyone but a “small circle of people”, it’s said that his WrestleMania opponent will be someone “totally unexpected”.
