As reported by The Herald Sun, Briggs has impressed rival clubs across his three matches in orange and charcoal this year following his debut in Round 9.
Briggs has been a formidable inclusion for Leon Cameron's side in 2021, but has again found himself toward the back of the pecking order - having not been selected since Round 15.
The 21-year-old is placed behind fellow 2021 debutant in Matt Flynn, while first-string ruck Braydon Preuss remains sidelined through injury.
Briggs' position at West Sydney could spark interest of clubs keen on adding height to their list, with the Suns, Bombers, Saints and Lions all tipped to do so.
The Lions are reportedly looking to fill the void left by injured forward Eric Hipwood, who is expected to miss the next 12 months with an ACL injury.
Briggs can be utilised as a flexible role player, moving both forward and into defence in minutes outside of the ruck.
According to The Herald Sun's report, Brisbane won't be looking to part ways with either of their first round picks - currently placed at 14th and 18th overall.
Briggs, who is unsigned past this season, could be seen as a bargain target for the Lions given his position at the Giants and limited amount of games.
