This is something you never want to see, an unfortunate part of fighting sometimes, especially when they're teenagers.
Yesterday, the North Bay Battalion took on the Sudbury Wolves in the back half of a home and home, things started to beat up during a scrum and Seattle Kraken prospect Ty Nelson took on Andre Anania and before the fight really starts, Nelson loses his helmet, gets tagged a few times and ends up smacking his head off the ice; take a look.
While I believe fighting belongs on hockey, that doesn't mean this kind of thing happening isn't both really scary and unfortunate. Hopefully Nelson is okay and makes his way back sooner rather than later.
