It's a scene we don't like to see, but is inevitable in a contact game when players are skating full tilt toward each other. Winnipeg Jets rookie Patrik Laine had his bell significantly rung on Saturday by Buffalo Sabres defenseman Jake McCabe. It was a clean hit, but Laine has some level of concussion.
As we know in the injury department, that can be as serious as a couple of days to clear the cobwebs or an indefinite period of time for the brain to heal. Each and every concussion is different.
