Rick Nash absorbed a blow to the head due to Brad Stuart's hit on Tuesday. Nash, who dealt with a concussion in February, attempted to stay in the game, but ultimately decided to call it a night. "It just didn't feel right," Nash said. "I could feel it. Any time you get a head shot you're concerned. It's not a good feeling." He should be considered day-to-day for now, but obviously this is very troubling news.
