Calgary Flames forward Sven Baertschi will be out of the lineup for at least a few games due to a hip flexor injury.

The 20-year-old native of Bern, Switzerland is listed as week to week, the NHL team announced Thursday.

"I was skating and my left skate seemed to have caught a rut in the ice and my legs kind of went into a splits position," Baertschi said in a release. "I felt pain immediately and left the ice to have it checked. It's very disappointing to learn that it's a hip flexor injury that will keep me out of the lineup."
