10 Things WWE Wants You To Forget About WrestleMania 31

5. The Brock Lesnar Blading Controversy

Did he or didn't he? The gif below suggests that the referee handed Roman Reigns a blade, who then passed it onto The Beast before his skull made contact with the ring post. Although when the incident happened it certainly looked like Lesnar was legitimately busted open the hard way when his head hit the post, it's impossible to know for sure. Nevertheless, WWE are now strongly against blood appearing in any of their main event matches. Or so we thought before The Undertaker and Brock's matches towards in the Autumn of 2015. Seeing colour in the main event of the biggest PPV of the year certainly was a huge shock and, given company stance on the issue, is something Vince McMahon, presumably, wants you to forget.
