The 33-year-old spent Sunday night in a St. Paul hospital following the Flames' 4-3 loss to the Minnesota Wild, undergoing tests after taking a shot off the back of his neck.
"I think any time you see a player that's taken off on a stretcher, obviously it plays on your mind," Flames assistant coach Dave Lowry said.
At 5:20 of the second period, Langkow was checked in front of the Minnesota net by Wild defenseman Greg Zanon. With Langkow's head down as he fell forward, Calgary defenseman Ian White fired a point shot that hit his teammate at the base of the neck in between his shoulder blades.
Langkow, who is out indefinitely, lay motionless on the ice for 10 minutes before being carried off on a stretcher.
"I think everyone was just scared," said forward David Moss, who watched as Langkow was strapped to a backboard and wheeled off the ice. "Not knowing what was going on, not seeing him move was a scary moment."
The Flames later found out that Langkow had feeling in all his extremities.
"I think after the period we found out he had movement and feeling," Moss said. "It was a great relief."
"You never want to see that," defenseman Cory Sarich said. "It's scary, especially when it's a teammate and a guy you're close with. It's freaky and really scary, but (we're) just glad to hear he's doing well and that's the main thing."
