ADELAIDE has received a boost on the eve of the finals, with four players recommitting to new two-year deals.
Forward Riley Knight and defenders Jake Kelly, Alex Keath and Tom Doedee have signed until the end of 2019.
However, the Crows are still yet to lock in their two biggest targets, defender Jake Lever and forward Mitch McGovern, to new contracts.
Knight, Kelly and Keath played in the Crows' 43-point win against Essendon at Etihad Stadium last Saturday night, while Doedee is yet to make his AFL debut.
"It's a great reward for Riley, Jake, Alex and Tom," Crows general manager list management and strategy Justin Reid said.
"All four are very team-orientated players, who are willing to do whatever it takes to help the club succeed and we look forward to seeing them continue to grow.
"We have developed a learning environment at Adelaide where we want to give players every chance of getting the best out of themselves."
Knight has played 26 games for the Crows since being selected with the 46th pick in the 2013 NAB AFL draft.
The 22-year-old, who can play on the wing or half-forward, has played 14 games this year and has also been used as a tagger.
Kelly, also 22, has shaken off a difficult season last year to cement himself in the side as a reliable defender.
He has conceded less than a goal per game to his direct opponents and is averaging 15 possessions per game at 85 per cent efficiency.
Keath has taken his chance with both hands since being elevated off the rookie list, the 25-year-old key defender looking at home in his four games.
The former state cricketer was recruited to the Crows as a category B rookie at the end of 2015.
He was outstanding against the Bombers, taking an equal team-high 11 marks and doing a great job on spearhead Joe Daniher.
Doedee, 20, was a shock selection when taken by the Crows with the 17th overall pick of the 2015 draft but has turned in some strong performances across half-back in the SANFL this year.
