It’s possible that Chytil was fine and that the Rangers made the decision that with a 3-1 lead and the 25-year-old’s history of concussions, they would be cautious and not play him in the third period. If that’s the case, however, why would they have played him for one shift late in the second?

As concern grows about Chytil's future even without a long-term diagnosis, the Rangers might need to start thinking about filling his spot.
