North Melbourne have announced midfielder Jared Polec has not been offered a new deal beyond 2022.

Polec joined the Roos on a long-term deal in a move from Port Adelaide at the end of 2018 and would play 42 games in four seasons at Arden Street.

North Melbourne was Polec's third club, having begun his career with Brisbane before moving to the Power.

Polec made his debut with the Lions in 2011 and would leave the club ahead of the 2014 season after 16 games with the Queensland club.

His move to South Australia would see Polec hit career-best form, averaging 25.14 disposals per game in 2018 - his final year at Alberton.

Polec switched to the Roos on a lucrative deal, but saw his spot on North's list slide and was moved to the Rookie List last year.

12 months on, he has been cut by the club despite being contracted for 2023.

“Unfortunately, for a variety of reasons, Jared hasn't been able to recapture the form he showed in his first year at the club,” Roos list boss Jade Rawlings said in a club statement.

“We made the decision to re-draft Jared this time last year after he was initially delisted but things haven't worked out for him or the club since then.

“As a result, we'll take four selections into the national draft and we'll have added flexibility with our rookie list due to the two extra picks that came via the AFL's assistance package.”

Polec joins Jed Anderson (delisted), Atu Bosenavulagi (delisted), Kyron Hayden (delisted), Jason Horne-Francis (Port Adelaide Power), Tom Lynch (retired), Matthew McGuinness (delisted), Kayne Turner (delisted), Josh Walker (delisted) and Patrick Walker (delisted) in departing the Roos this year.
