Narkle remains out of contract for 2021 and could be delisted at the end of the season, with a number of clubs eager on the pacey Cat.
The Geelong utility has played just 17 games for the Cats since being drafted in 2016 and has shown potential to warrant a starting spot on another side’s list.
Clark, who is contracted with the club until the end of the 2022 season, could look for a move home to Western Australia given his limited minutes under Chris Scott.
The former first-round selection played 18 games in his debut season last year, but after sustaining injuries and falling behind in selection discussions, the 19-year-old could request a move away from Kardinia Park.
According to The West Australian, both the Eagles and Dockers are “monitoring” the Geelong pair for the upcoming trade and free agency windows.
