Blackhawks coach Joel Quenneville was admitted to a hospital Wednesday morning after being taken to the emergency room a night earlier night with an "undisclosed health concern." "Joel presented severe discomfort late last night at his home in suburban Chicago," Blackhawks team physician Michael Terry said in a statement. "He went to the emergency room and was admitted early this morning. "He is currently in stable condition and is being treated for an undisclosed health concern today, not of cardiac nature. Further testing is ongoing and we will provide an update when possible."
