Kings have not signed him yet. I don't know what kind of contract he has over there with his parent KHL club. If I recall most discussions were he needed to mature a lot physically. So I'm not sure what the thought process is for next season.
Eliteprospects says "Contract 20/21" so he will play in Russia this and next year. Hopefully in the KHL or at least in the VHL. MHL is for juniors.
