Calgary left winger Alex Tanguay left the Flames' game Friday midway through due to a knee injury after he became tangled with the Coyotes' Kyle Chipchura at the boards. Tanguay's left foot was caught as he fell and his scream while his leg was twisted could be heard all the way up to the press box. "It doesn't look good," Flames coach Bob Hartley said. "The doctors were around him when I got in (the room). I didn't see it, but Marty Gelinas saw a replay somewhere and said it's ugly."
