Kahkonen was assigned to AHL Manitoba on Sunday, per the NHL media site.
Due to the absence of Connor Hellebuyck (rest), Kahkonen was the backup behind Eric Comrie in Saturday's 4-3 shootout win over St. Louis. According to Mitchell Clinton of the Jets' official site, Hellebuyck participated in Sunday's optional practice, clearing the way for the 31-year-old netminder's return to the lineup in Monday's home game versus San Jose.
