Kokko was reassigned to AHL Coachella Valley on Sunday. Kokko's demotion comes at the expense of Philipp Grubauer being recalled from the Firebirds in a corresponding move. Kokko allowed two goals on six shots in his NHL debut in relief of Joey Daccord in a 7-2 loss to the Blues on Feb.
Ales Stezka was called up to the Seattle Kraken on Wednesday and will remain as the backup goaltender, with Philipp Grubauer continuing in the AHL with the Coachella Valley Firebirds.
