West Coast's desire for more early selections in this year's national draft created the opportunity for the Bulldogs to convert Essendon's two second-round draft picks for Stringer into a pick inside the first round.

The Bulldogs appear to have come to terms with the fact that Essendon's pick 25 and 30 are the best they can hope to receive from the Bombers for Stringer and are negotiating a complex pick swap with the Eagles.

Under the deal, the Bulldogs would give the Eagles pick 9, 25 and 30 in exchange for West Coast's pick 13 and a swap of future draft picks.

Meanwhile, the immediate future of several contracted players will hang on discussions planned for Wednesday, with the Brisbane Lions set to resume talks with Adelaide in an attempt to convince the Crows to trade Charlie Cameron.

If the Crows decide to retain Cameron, who has a year remaining on his contract, they face the risk of losing him for little return at the end of next season.

Fremantle are understood to have not moved on their request for pick 2 for Lachie Weller.

Weller is contracted for next year but has asked to be traded back to the Gold Coast, where he was living when he was drafted.

The Dockers, meanwhile, are seeking to trade in contracted Giants defender Nathan Wilson and uncontracted Suns forward Brandon Matera.

The Dockers want to keep those deals separate to the Weller request and possible trade, with discussions on Wilson focusing on Greater Western Sydney receiving a future second-round pick for the running defender.

GWS dismissed St Kilda's approach to trade for contracted defender Adam Tomlinson for a future second-round draft pick and a third-round pick this year.

The Giants have said from the start of the trade period that Tomlinson was contracted and off limits to trade.

Carlton met the Giants on Tuesday to discuss Matthew Kennedy's possible trade to the Blues.

The Blues originally offered pick 40 but the Giants are holding firm on their request for a second-round pick and remain hopeful of receiving that for Kennedy, who was a first-round pick in 2015.

After putting himself on the market, Brisbane Lions tall Josh Schache is preparing to resume his career in Queensland after no serious suitor emerged on Tuesday.

With less than two days remaining in this trade period, time is running out for a Victorian club to make a play for the 19-year-old, who has played 27 games in two seasons with the Lions.

Fremantle's Harley Balic will be traded to Melbourne on Wednesday morning, with pick 66 likely to change hands for the Docker, who was pick 38 in the 2015 AFL draft.

West Coast acquired Port Adelaide midfielder Brandon Ah-Chee and a future fourth-round pick in exchange for a future third-round selection.
