According to Mike Johnson of PWInsider, Lesnar legitimately smashed through the chamber door, and it wasn’t a planned spot.
“Brock Lesnar smashed through a legitimate Elimination Chamber door to enter the EC match and we are told that was not a planned spot. That is one scary man.”
Brock Lesnar is set to square off against Roman Reigns in a winner take all match at WrestleMania 38. It remains to be seen who will end up becoming both the WWE and Universal Champion at WrestleMania 38.
