The 21-year-old Carruth did not appear in any preseason games with the Blackhawks. He is a 2010 seventh-round draft choice of the Blackhawks.
Carruth was 30-7-2 with a 2.06 goals-against average and a .929 save percentage with the Portland Winterhawks of the WHL last season. He is expected to share the IceHogs' goaltending duties with Antti Raanta and Kent Simpson to begin this season.
The Blackhawks’ active roster now includes 46 players, including 28 forwards, 14 defensemen and four goaltenders.
