Potter was recalled from AHL Adirondack on Wednesday, Scott Cruickshank of the Calgary Herald reports. Tyler Wotherspoon was unable to break into the Calgary lineup as a seventh defenseman, so he'll head back to the minors in a corresponding move in an effort to pick up more ice time. The Flames aren't nearly as keen on carving out a regular lineup spot for the 31-year-old Potter, who looks to be little more than organizational depth. He'll stick with the team only as insurance in the event of an injury on the blue line.
