Adelaide ball-magnet Matt Crouch will remain a Crow for at least another four seasons, after penning a three-year contract extension with the club.

The 22-year-old was already contracted for the 2018 season, and his extension will now see him tied to Adelaide until at least the end of 2021.

Crouch enjoyed a breakout year in 2017 and was one of the game's premier midfielders, as he walked away from the season with both an All-Australian selection, and the Malcolm Blight Medal as Adelaide's best and fairest.

Crouch broke the AFL record for most disposals in a season with 825, and tallied over 30 touches in 19 of his 25 games.

“I’m really pleased to be able to wear the Crows colours for the next four years at least,” Crouch told afc.com.au.

“The Club is a fantastic place to be with a committed playing and coaching group who are determined to achieve success.

“I’m excited for what the future holds and look forward to the start of Season 2018 already.”

Adelaide's General Manager List Management and Strategy Justin Reid was equally as excited to have Crouch sign on, and is looking forward to seeing the midfield dynamo continue to grow as an on-field contributor.

“Matt has developed into one of the premier midfielders in the competition and to have him around until at least 2021 is a great result for the Club,” Reid said.

“He has not only bought into but led the way with the Club’s team-first culture and helped create a really positive environment.

“At only 22 years of age his best football is still ahead of him and we are excited to continue to see him grow as a player and a leader.”

Crouch has played 72 games for the Crows since making his debut in round three, 2014, and is averaging 26.7 disposals and 4.6 clearances per game over his career.
