Pro wrestling is always dangerous because you never know what can happen in the ring. Some moves are far more dangerous than others. The bucklebomb was on the banned moves list in WWE, but that is no longer the case.
Seth Rollins hit Murphy with a bucklebomb during their match on SmackDown this week. That match had a ton of build with no advanced notice prior to the match. It was noticed by a lot of fans that Rollins pulled off that dangerous and previously banned move.
During Wrestling Observer Radio, Dave Meltzer noted that Vince McMahon removed the bucklebomb from WWE’s banned moves list. This is why Rollins was allowed to use it with Murphy.
Kairi Sane was most recently injured by Nia Jax when a bucklebomb spot went wrong. Seth Rollins also famously ended Sting’s career with that very move as well. Now the move is back, but it might not be a good idea to expect it on a very frequent basis.
