YOUNG Adelaide defender Fischer McAsey has resisted overtures from Victorian rivals to sign a fresh deal with the Crows.

Victorian-based clubs were understood to be circling the second-year Crow, the No.6 pick at the 2019 NAB AFL Draft.

But McAsey has signed two-year contract extension to remain in Adelaide until the end of the 2023 season.

"I'm excited by what we're building at Adelaide," said McAsey, who played 10 games in his maiden campaign year last season when the Crows took the wooden spoon.

"My faith in the club has never wavered and I have enjoyed settling into Adelaide over the first two years.

"I want to be part of it ... we have a great group of young players who are coming through together and we are driving each other to get better."

The 197cm McAsey has yet to play an AFL game this season but was a vital part of future planning, Adelaide's list manager Justin Reid said.

"We have a lot of belief in Fischer and value him incredibly highly both as a footballer and a person," Reid said.
