Adelaide defender Tom Doedee has suffered a suspected ACL injury in the Crows' clash with Hawthorn on Saturday afternoon.
Doedee was involved in a tackle with Hawthorn veteran Jarryd Roughead, before immediately going down with the injury.
"It's a suspected ACL, not good news for Tommy," Crows' head of football Brett Burton said.
"He's an outstanding character, he's obviously disappointed ... but he's staying upbeat."
Crows defender Tom Doedee will not return after injuring his knee against the Hawks.
