Granlund (undisclosed) left in the second period of Friday's preseason game and did not return, the Calgary Herald reports.

Analysis:

Granlund is one of the brighter prospects the Flames have, as he was one of the top AHL players in Abbotsford last year and also had three points in seven games with Calgary. He struggled with a shoulder injury at the end of last season, so hopefully the injury is not to that shoulder again.
