The team annouced Monday that Langkow will be out indefinitely with a neck injury.
Langkow was not moving as he was removed from the ice on a stretcher. The 13-year veteran remained on the ice for nearly 10 minutes before leaving. He was injured at 5:20 of the second period of Sunday's game against the Minnesota Wild.
Langkow was checked from behind by Minnesota defenseman Greg Zanon and hit Wild defenseman Marek Zidlicky as he lost his balance and fell forward. With Langkow's head down as he fell, Calgary defenseman Ian White fired toward the net and hit his teammate.
