Chris Tanev appears to be out after taking puck to the head (video)

Lots of concern for Calgary's Chris Tanev Monday night after he left the Flames' game against the Montreal Canadiens. Tanev was out to kill a 5-on-3 when he blocked a hard shot by the Habs Nick Suzuki with what looked to be the side of his head. As the camera zoomed in on Tanev, he appeared to be out cold. His eyes were closed and he was completely motionless for some time. Tanev eventually left with the help of three of his teammates. He looked very dazed the entire time he was leaving the ice. Let's hope he's ok.
