Fremantle are said to be making a move for former Melbourne and Carlton defender Oscar McDonald through this year's delisted free agency period.

McDonald last played in the AFL in 2022 with the Blues, whom he spent two seasons with for a return of five games as injuries played their part in his limited stint at Princes Park.

The 27-year-old earned a reprieve with Carlton after being delisted by Melbourne at the end of 2020, with McDonald departing the Demons following an 81-game spell with the club that drafted him in 2014.

McDonald would sign with VFL outfit Williamstown following his Blues departure and enjoyed a stellar first season with the Seagulls, earning a place at full-back in the competition's Team of the Year.

The key defender was on the radar of AFL clubs for this year's Mid-Season Draft but couldn't land at his third club, however the Dockers are now expected to sign the former Vic Country talent.

According to's Riley Beveridge, Fremantle are looking to swoop on McDonald as a delisted free agent - with the signing window to open next Wednesday.

McDonald is believed to have met with the Dockers and undergone a medical with th Western Australian club.

The Dockers lost veteran defender Joel Hamling to Sydney this off-season via free agency and could view McDonald as a similar depth option to support the likes of Luke Ryan, Alex Pearce and Brennan Cox.

McDonald won't be the first delisted free agent to earn another AFL chance, with North Melbourne already confirming the addition of former Sydney defender Toby Pink.

Ex-Swans ruckman Sam Naismith has also been linked to a potential reprieve as Richmond looks to bolster their ruck stocks for 2024.

Delisted free agency will commence on November 1 and will run for one week, with the period open again from 9:00am-5:00pm (AEDT) two days later. The period will again recommence at the completion of the National Draft on November 21.
