A GIF from Brock Lesnar vs. Roman Reigns at Wrestlemania 31 from Sunday is circulating that appears to feature the referee handing Reigns something. Speculation suggests it was a razor blade, as Brock added color (made himself bleed) shortly after a spot by the ring post.
You can watch the GIF that shows the referee hand Reigns something below:
Whether or not Lesnar bladed is unknown and it probably won't be known. WWE officially banned blading in 2008 and have taken precautions to stop bleeding during matches due to blood diseases such as HIV and Hepatitis C.
We caught CM Punk using a razor blade to add color during a match back in 2012, when it was also banned.
Thanks to Jesse Sherwood for bringing this to my attention.
