Kokko was sent down to AHL Coachella Valley on Friday.
Kokko saw action in three NHL games during his stint with the Kraken, posting a 1-2-0 record and 3.03 GAA. The Finnish netminder put up much better numbers with the Firebirds, going 18-10-2 with a .903 save percentage in 34 minor-league outings. With both Joey Daccord (lower body) and Philipp Grubauer (lower body) under contract next year, Kokko figures to be hard-pressed to see significant opportunities in the NHL.
