The glass landed directly on the man's head. Trainers rushed across the ice as soon as they were able to attend to him. They decided it would be best to take the attendant out on a stretcher with a neck brace on. It was likely precautionary, and we hope the attendant is alright.
I understand that it was accidental, but it's just a cautionary tale as to why it's important to control yourself. We don't know the extent of the damage yet, but my gut tells me that this one could have ended a lot worse.
