When it comes to possible concussions and/or head injuries, it’s wise to use caveats. Sidney Crosby* stands as one of the prime examples for why we say “Player X seems OK … for now.” Many of us hold sad memories of his early concussion issues, as Crosby suffered from a David Steckel hit, only to see things worsen after a collision with Victor Hedman. So, in cases like Thursday, you have to be careful not to assume too much about Crosby being OK. But at this moment, it seems like this accidental-looking collision with Jordan Eberle won’t have longer-reaching ramifications
