A scary moment was barely avoided during a WWE taping of Smackdown at the Dunkin Donuts Center in Providence, RI, when a fan jumped the railing and rushed at Dean Ambrose. Thankfully, the fan was tackled to the ground by security. It’s unclear as to what the fan was holding, but some have suggested that it was a knife.

This is not the first time this year a crazed fan has gone after a WWE superstar. In July, the WWE was in Europe when a fan threw a briefcase and hit Roman Reigns on the head.
