The broadcast speculated it was a possible concussion, but I'm not sure it was a shot to the head. It looked more like Krejci was favoring his shoulder, but he hasn't come back yet.
UPDATE: Krejci has returned to the game. PHEW. He came back at the first stoppage after the 14-minute mark. CRISIS AVERTED.
