Mikheyev came to training camp injured after undergoing season-ending knee surgery in January of this year. However, he was practicing with the Canucks' third group and was expected to move up over the weekend in a non-contact jersey. Why he left and when he'll be back is completely unclear at the moment.
Mikheyev signed a four-year deal with the Canucks in 2022 worth $4.75 million per season. Before that, he played three seasons with the Toronto Maple Leafs after spending several years in the KHL in Russia.
