Adelaide have confirmed defender Tom Doedee has ruptured his anterior cruciate ligament in his left knee and will require surgery.
The talented defender injured his knee attempting to tackle in the second quarter in the Crows clash against Hawthorn on Saturday.
Doedee is the second player to suffer an ACL injury in round one, after Richmond defender Alex Rance's season was cut short on Thursday night.
The 22-year-old will likely miss the remainder of the season.
Doedee has played 21 games for the Crows since making his debut in round one last year.
