As seen at the WWE Hell in a Cell PPV, both Brock Lesnar and The Undertaker were bleeding during the main event of the show. Lesnar and Taker did not blade but rather were busted open the hard way. Lesnar ran into the ring post (the same spot he did at WrestleMania 31), and Taker was busted open after Lesnar took his glove off and punched him in the head.
There were rumors online that they bladed, which is NOT true at all. WWE issued this statement the night after WrestleMania 31 about Brock Lesnar bleeding in his match with Roman Reigns.
“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.”
