Hutchinson will fill in for backup Petr Mrazek, who is out for at least two weeks after sustaining a groin injury during Thursday’s 3-2 loss on the road to the Ottawa Senators.
Toronto was too tight to the cap ceiling to call up Hutchinson from the Toronto Marlies in time for Saturday's rematch against Ottawa at home. Instead, the Maple Leafs signed University of Toronto Varsity Blues goalie Alex Bishop to a one-day amateur tryout. Bishop served as the backup to Jack Campbell, who made 20 saves in the 3-1 victory.
Hutchinson, 31, appeared in eight games with the Maple Leafs last season and posted a 4-2-1 record with a 2.42 goals-against average and .919 save percentage.
