After a bit of an unclear few hours today, the Calgary Flames have announced their roster moves stemming from the injuries they faced last night against Montreal.

Center Matt Stajan has been placed on the injured reserve with a knee injury and is expected to be out for approximately six weeks, per the team’s release. To take his place on the roster, the club has recalled Markus Granlund from the American Hockey League’s Adirondack Flames.

Granlund, 21, was Calgary’s second rounder in 2011 (and is the younger brother of Minnesota Wild forward Mikael Granlund). He played his first year of North American pro last season and was pretty damn good – he had 44 points in 52 AHL games with Abbotsford and 3 points in 7 NHL games before a shoulder injury ended his season. He returned from the injury for the AHL playoffs, though. He’s got 5 points in 8 games this year for Adirondack.

Right now, Stajan, Raymond and Joe Colborne are sidelined. The fact that Colborne isn’t on the IR doesn’t mean he won’t eventually be on it; you’re placed on IR retroactive to when you were injured, so depending on his progression in his recovery, they may just put him on to bring up another AHL body.

Officially, Stajan is gone for 6 weeks (or so), Raymond is week-to-week and Colborne is day-to-day. But anybody who’s followed injuries around the league can probably tell you that those are always subject to change.
