St Kilda's pursuit of Fremantle star Bradley Hill will go down to the wire after the Saints were unable to include the three-time premiership winger in the deal that landed Dougal Howard and Paddy Ryder from Port Adelaide.
The Power pair were secured on Tuesday, but Hill will have to wait until Wednesday when the AFL trade period closes at 7.30pm AEDT to learn his fate.
"We respect that Brad is contracted and is a really talented player, but there is an opportunity there and we think we're inching closer with Freo," Saints list manager James Gallagher told AFL Trade Radio on Tuesday.
"There is a deadline to reach so we'll know in 24 hours or so whether we've been successful or not.
"It's been reported that Fremantle have some level of interest in (Blake Acres) ... but it's too early to speculate if he will or won't (be part of that deal).
"We're pretty open-minded, as are Fremantle, with what it will take to get a fair deal done."
The Dockers have been intent on securing two first-round picks for Hill, but the Saints aren't willing to part with their 2020 first-rounder as well as their first call at this draft.
Gallagher confirmed Sydney's Zak Jones and Richmond's Dan Butler will also be on his club's radar on deadline day.
The Saints secured Howard and Ryder as well as pick No.10 and a future fourth-round selection from the Power in exchange for picks 12 and 18 and a future third-rounder.
Several deals were finalised on the penultimate day of trade period.
A day after Eddie Betts was traded to Carlton, Adelaide's list overhaul continued with Hugh Greenwood sent to Gold Coast for future third and fourth-round picks and Sam Jacobs dealt to GWS for a future fourth-rounder.
Alex Keath's move to the Western Bulldogs and finding a home for Josh Jenkins remain on the Crows' agenda.
Adelaide, who announced Matthew Nicks as their senior coach on Tuesday, snared ruckman-forward Billy Frampton from the Power for a future fourth-round draft selection.
Former No.1 draft pick Jonathon Patton's switch to Hawthorn was formalised with GWS accepting a future fourth-round pick in return, while Collingwood brought in back-up ruckman Darcy Cameron from Sydney for a swap of late picks.
Melbourne have two top-10 picks at the draft after adding North Melbourne's eighth overall selection to their No.3 pick.
North effectively turned one draft pick into three after the Demons sent picks 26, 50 at this draft and its future first-round selection to the Roos.
With the trade window set to close, several deals continue to be negotiated.
The stand-off between Essendon and the Swans over Joe Daniher continues, with the Bombers unimpressed with the offer of picks five and 25 from Sydney.
The Blues are still working on securing Jack Martin from Gold Coast and Tom Papley from Sydney.
The Dogs are looking to add Josh Bruce from St Kilda but are yet to agree to terms, with Jack Steven's move to Geelong also up in the air.
James Aish appears headed to Fremantle, with the winger undergoing a medical at the WA club, as Collingwood looks to clear salary cap space to sign Brodie Grundy, Jordan De Goey and Scott Pendlebury to new deals next year.
