The Eagles remain the frontrunners to secure Yeo, who has been offered a three-year deal to join the club.
The Dockers, however, appear poised to make an offer should negotiations between West Coast and the Lions break down.
It is believed Fremantle is not willing to part with anything higher than its second-round pick (currently No.33) in the 2013 NAB AFL Draft for Yeo, who has requested a trade to his home state.
West Coast, meanwhile, could offer its second-round selection (currently No.24), with the Lions chasing a pick in the early 20s.
On a day when Lance Franklin's move to the Sydney Swans was finally completed, there was little else official of note but plenty went on behind the scenes.
Fremantle midfielder Viv Michie has returned to Victoria to weigh up his future, with offers understood to be on the table from the Dockers and Melbourne.
Michie, who was recruited with pick No.44 in the 2010 NAB AFL Draft, has only played one game in three seasons because of persistent foot injuries.
He finally overcame his injury issues in 2013 and averaged 26 disposals in 16 games with WAFL club Peel Thunder, winning the best and fairest award.
St Kilda had shown interest in the 21-year-old, but AFL.com.au understands his decision will be between the Demons and Fremantle, which is keen to retain the on-baller.
Contracted forward Josh Mellington has requested a trade and the Dockers are willing to help him find a new home. His future, however, is likely to remain unclear until the second week of the Gillette AFL Trade Period.
While the Bombers have publicly declared David Myers off the table, it is understood clubs still view him as gettable if a pick inside the top 10 is involved.
St Kilda and the Demons remain interested in securing the big-bodied 24-year-old.
Fremantle and West Coast, however, have not expressed interest in luring him back to his home state.
Myers held discussions with the Bombers last week to establish what role they saw him playing in 2014, and it is believed they could offer no guarantees to satisfy his wish for increased midfield time.
If Melbourne had been willing to part with its pick No.2 as part of a deal for Myers and teammate Travis Colyer, it is considered likely both young Bombers would have been playing with the Demons in 2014.
Colyer signed a two-year contract extension with the Dons on Tuesday.
Sam Docherty has nominated Carlton as his preferred club after the No.12 selection from the 2011 NAB AFL Draft walked out on the Brisbane Lions.
The Blues have offered the Lions players rather than draft picks.
It is understood North Melbourne and Essendon are also interested in the No.12 pick from the 2011 NAB AFL Draft, but they are yet to get on the front foot.
Collingwood remains interested in Patrick Karnezis, but the Lions midfielder is not a priority for the Magpies at the moment.
Hawthorn, meanwhile, still leads the charge for ruckman Billy Longer.
The Hawks have offered the Lions contracted midfielder Shane Savage, however that is considered unlikely to get a deal done.
Young Lion Jared Polec, who has requested a move home to South Australia, has drawn offers from both Port Adelaide and the Crows.
The Power have offered their second round pick (currently No.30), but the Lions are seeking a first-round pick in exchange for the 20-year-old.
Carlton has shown interest in delisted Western Bulldogs midfielder Daniel Cross, joining Melbourne in talks to sign the 210-game veteran.
Coach Mick Malthouse has a link to the 30-year-old after coaching the inside midfielder in the 2010 International Rules tour of Ireland.
