WWE issued the following statement last night in regards to online speculation of blading by Brock Lesnar during his match with Roman Reigns at Wrestlemania 31:
“WWE programming is TV-PG and we don’t permit intentional bleeding. The communication or contact between our performers and referees is part of our safety protocol. That said, unintentional blood sometimes occurs, and we do our best to minimize.”
