WWE has banned the use of the buckle bomb, otherwise known as a power bomb into the turnbuckles.
The decision was first reported by PWInsider and verified by our Bryan Alvarez.
It's unclear why the decision was made now, but an April 20th Raw match featured such a move delivered by Nia Jax to Kairi Sane that drew significant criticism as Sane's head hit the middle turnbuckle awkwardly.
The most well known incident with the move was at 2015's WWE Night of Champions pay-per-view as then-WWE Champion Seth Rollins delivered the buckle bomb to Sting, injuring his neck. It was later learned the WWE Hall-of-Famer had spinal stenosis and while not blaming Rollins, he said on a podcast with Ric Flair that he was lucky "a catastrophe" didn't happen that night.
The buckle bomb joins the piledriver, chair shots to the head, and several other moves on the current banned list. It's possible the move could return someday as the shooting star press and Rollins' curb stomp both were allowed back after briefly being banned.
