It’s interesting because Sullivan came out and said it wasn’t the same as his last injury but he never actually said it wasn’t a concussion...if you look at his practice history, he was skating a couple days in a row without contact and then didn’t skate....that’s a typical pattern for concussions if headaches or other symptoms reoccurred...could it be some other type of upper body injury? Maybe something like a slipped disk in his neck where the pain comes back but not much else...I mean if he had a shoulder or rib, hand, arm , or something like that then that pattern wouldn’t make sense....
