Diaz is in danger of missing Saturday's game against the Oilers, after suffering an undisclosed injury during Thursday's loss to the Blues, Pat Steinberg of 960 The FAN reports. The Flames recalled Tyler Wotherspoon from AHL Adirondack, hinting that Diaz will likely miss at least one game. Calgary does have Sunday and Monday off, before returning to action against the Coyotes on Tuesday.
