The 20-year-old was originally raised in Western Australia before Geelong drafted Clark in 2018 with the 15th pick.
Despite playing 18 games in his debut season, Clark has struggled to cement a permanent spot in the Cats' line-up in recent years while also battling injuries.
Fremantle reportedly looked to lure Clark back to his home state last year after the out-of-favour Cat managed only three games in 2020.
But despite admitting frustrations during last year's hub life, the speedster went on to sign a contract extension with the club that sees him through to the end of 2022 at the Cats.
After a strong pre-season, Clark played in the first four games in 2021 but has since been in-and-out of the side.
Off-season recruits in Isaac Smith and Shaun Higgins have pushed the Western Australian out of Geelong's best 22 since Round 9, and he was not considered as an emergency in last Thursday's game against Port Adelaide.
For Fremantle, Clark offers an exciting prospect to compliment an already young list.
With their own concerns regarding the future Adam Cerra, the Dockers will be hoping the temptation of a return home and consistent playing time will be enough to coax the contracted Clark away from Kardinia Park.
Freo will head into the bye in Round 14, whilst the Cats will take on the Western Bulldogs at 7:50pm on Friday at GMHBA Stadium.
