Chicago Blackhawks forward Jujhar Khaira was stretchered off the ice after he was leveled by New York Rangers defenseman Jacob Trouba on Tuesday night. The Blackhawks said Khaira suffered an “upper-body blow” and was taken by ambulance to Northwestern Hospital for further testing. Khaira’s head was down as he gathered in the puck 6:10 into the second period, and Trouba appeared to drive his right shoulder into his chin.
