ADELAIDE forward Mitch McGovern has re-signed with the Crows, extending his contract until the end of 2020.

It's a major coup for the Crows to lock in the 22-year-old on the eve of the finals after drawn-out negotiations to retain the high marking youngster.

McGovern was reported to have attracted interest from Fremantle who were keen to lure the West Australian back to his home state.

However McGovern, who has played 35 games for the Crows, decided to stick with the club that selected him at pick No.43 in the 2014 NAB AFL Draft.

"I love the playing group I’m playing with, but also the staff and everyone involved," McGovern told the club website.

"The culture is fantastic here. It’s one of the best-run clubs that I can see and I’m glad to be a part of it. 

"I’m pretty excited for the future ahead." 

Star Crow could miss final with appendicitis

His outstanding pack mark and after-the-siren goal that drew the tight clash between Collingwood and Adelaide in round 19 showed McGovern has an x-factor and he has kicked 51 goals across his career.

The Crows' only out-of-contract star going into the finals now is defender Jake Lever who is believed to be considering offers from Melbourne and Collingwood.

The 21-year-old Lever, who has played 53 games with the Crows, is understood to no longer be considering the Western Bulldogs but remains open to the prospect of a move.

Adelaide finished on top of the ladder and will play a home final against Greater Western Sydney next Thursday night to start its premiership campaign.
