A second straight-sets finals exit in three years has the Lions desperate to remain inside their premiership window.
After bringing in big-name recruits Joe Daniher and Lachie Neale in recent years, Brisbane are now looking to be thrifty with their trade targets, with rival clubs are reportedly aware of Brisbane's desire for another ready-made ruck option at the trade table.
Fort, who was unable to break into Geelong's senior side in 2021, presents a cheaper option to assist McInerney with ruck duties.
Despite being contracted at Geelong until the end of 2022, The Age has reported that the 204cm Fort is now on the Lions' radar.
Geelong is yet to indicate whether they would be open to trading the ruckman.
Meanwhile, the Cats are also preparing for youngster Jordan Clark to request a trade, with the West Australian meeting with Fremantle coach Justin Longmuir last week.
Tall forward Nathan Kreuger is also expected to leave the Cattery, with Collingwood looming as the most likely destination for the 22-year-old.
