There is a reason that most places surrounding a hockey rink have protective glass around them. Mostly for fan protection.
And if you've ever been to a hockey game in person, one of the more prominent signs you'll see is the one proclaming "Please pay attention while the puck is in play".
That being said, check out this video from last nights NY Rangers/NY Islanders game at Madison Square Garden.
You'll see, albeit from a distance, MSG Network on-ice reporter John Giannone "Take one for the team". He is the recipient of Marc Staal's flip towards the wall, which was the only protection Giannone had.
A little blood, but otherwise no serious injury was had.
Thanks NHL.com for the video:
