Canucks general manager Patrik Allvin said Friday night that the 28-year-old Russian forward tore the anterior cruciate ligament in his left knee in the team's first preseason game Sept. 25. Mikheyev will undergo surgery next week and is expected to be ready for training camp in the fall.
Mikheyev was originally listed as week-to-week with the injury and played 45 regular-season games, finishing with 13 goals and 15 assists. He scored in his final appearance Friday night, a 5-2 home victory over Columbus.
Mikheyev signed a four-year, $19 million contract as a free agent last summer.
