I wasn't going to post this until I had more info, but for those that don't know, Patrice Bergeron was just hit in a play yesterday, but it was up near his head and it seems to have triggered his severe injury from last year.
He was brought to the hospital and they said that they need to have the swelling go down (this is from an interview yesterday) to know what the damage is. I saw the hit and it wasn't really severe, but I think it's because Patrice (of course) was so badly injured.
