Brodie Smith is months away from a playing return for Adelaide, but the defender has been given the security of a long-term deal.
The Crows, who would have seen him come out of contract later this year, have secured him through to the end of the 2021 season.
I will be doing everything I can to get back out on the park with my teammates as quickly as I can.Brodie Smith
The skilful half-back, who ruptured his ACL in last year's qualifying final win against Greater Western Sydney, is hoping to be playing again before this year's finals.
Smith said it had been a difficult off-season for him after having a knee reconstruction, but to be able to agree to a new deal was comforting and exciting.
"Adelaide is just a great club to be a part of and I've formed some really close relationships with players, coaches and staff who are all trying to get the best out of each other," added the 2014 All Australian.
"I couldn't imagine playing football anywhere else and I will be doing everything I can to get back out on the park with my teammates as quickly as I can."
Smith was ranked No.1 at the Crows for metres gained last year, and Don Pyke's side will miss his run and drive off half-back and ability to push onto a wing.
But he started running pre-Christmas and the club have been encouraged by his progress.
List manager Justin Reid said Smith, who was second at the club for rebound 50s and effective kicks last season, had grown as a player and a leader within the group over the past few years.
"Brodie is one of the most damaging running defenders in the competition who has a unique ability to break the lines," added Reid. "He's approached his rehabilitation with a fantastic attitude and we look forward to him getting back to playing."
The 26-year-old was recruited with pick No.14 in the 2010 AFL Draft and has played 143 games, including 21 or more in each of the past four seasons.
Adelaide are 1000/1 to win the Grand Final.
The Crows are 5000/1 to finish in the top eight.
