The Flames have been struggling to shore up the goaltending situation this season as stalwart Miikka Kiprusoff struggled before going on injured reserve with a lower-body injury. Before his injury, the veteran netminder had a 3.24 goals-against average and .870 save percentage with the Flames falling to No. 28 in the NHL in goals-allowed.
Touted prospect Leland Irving was looked upon to play in Kiprusoff's place and struggled in two starts for the Flames, allowing eight goals and managing just a .879 save percentage while recording one win and one loss.
MacDonald has seen limited NHL action during his career but seemed to find a solid spot as Jimmy Howard's backup in Detroit. In 101 NHL games, MacDonald has a .903 save percentage and 3.04 GAA. MacDonald is expected to back up Kiprusoff, who is currently slated to return from IR on Wednesday against the Dallas Stars.
