It's a penalty in the new NHL where you can't hit a player from the blindside, however it wasn't a match penalty because he didn't hit him in the head. It was a very unfortunate accident in that Eller face planted on the ice. Hope he gets better soon.
The rules no longer say anything about blindside hits. Just hits where the head is targeted and the principal point of contact.
After seeing TSN's analysis of the video which shows that it's a clean body check with incidental head contact (which isn't illegal), and Eller played the puck before the hit, I can't figure out why the NHL is even having a hearing with Gryba, unless the Canadiens organization is just pitching a fit about it and the Commissioner is having the phone hearing just so they can say they looked into it. I'll be shocked if there is any punishment because of it. Well, not shocked, but appalled, because the hit was clean by the book, even if it resulted in injury.
Well....it is the whiny Habs. I saw nothing wrong with the hit. The outcome was unfortunate but not even remotely malicious. If he gets a suspension it is strictly due to Montreal bias. It did not look like he even tried to light him up like Torres last year. A suspension would be total BS.
