Smith back

Yeah I’ll admit I don’t know the rules of injury protocol to the minutiae but players come back after injuries like this : see Gabriel.  If its something like this it’s possible this is a longer term issue; maybe something carried over from college?  (Unfortunately CTE isn’t fully diagnosed while you’re alive but the lingering symptoms are evident).  Or maybe it’s not something triggered by physical injury and it’s emotional.  I think just before he posted that last tweet there was a death in either his family or a close family friend.
