I might be reading too much into the wording but it says "due to a neck condition." If it is the same was last season's injury before camp even started, then it could be something chronic. After first hearing about it back then, I was expecting him to be on LTIR last season too.
Yeah, I hope for his sake he can get treatment and live a normal life. They've made some remarkable improvements in disc replacement technology that doesn't require fusion. It seems like something like this would be a structural issue.
