We're four days into the trade period, with more deals getting done with each passing day as clubs, players and managers continue their negotiations.

Here's all the latest trade news, rumours and done deals from today's action...

Dogs could let Dunkley walk to PSD

Wantaway Bulldogs midfielder Josh Dunkley could be forced to find a new club through the Pre-Season Draft as negotiations between the Dogs and Brisbane fail to progress in favour of the Whitten Oval club.

The Dogs had demanded a pair of first-round selections on return for Dunkley two years ago when he had hoped for a move to Essendon, who were unwilling to give up that amount of draft capital for the Gippsland product.

But the same scenario is in place this year, with the Lions' requests in negotiations leaving the Western Bulldogs frustrated, according to SEN's Sam Edmund.

So much so that the Dogs have flagged they could allow Dunkley to remain unsigned come the end of the trade period and have the 25-year-old enter the open market through the Pre-Season Draft.

Brisbane held Pick 15 for this year's draft before moving the pick on for a pair of later selections for the 2022 and 2023 drafts in a trade with the Giants, further adding to the worrying talks with the Dogs.

DONE DEAL: Suns forward traded to Dockers

Forward Josh Corbett is officially a Docker after Fremantle and Gold Coast reached an agreement on Thursday.

The deal sees the Suns receive a future fourth-round pick in exchange for the 26-year-old.

After showing promising signs in season 2021 featuring in 16 games and kicking 23 goals, the 190cm forward couldn't break into a strong Suns' forward line in 2022 with Mabior Chol and Levi Casboult having excellent seasons.

Corbett would be a predominant key alongside Chris Burgess in the Suns' VFL side, kicking 25 goals in 12 games with the team reaching a preliminary final.

Eagles eye Houston as part of three-club trade

West Coast are said to have enquired about contracted Port Adelaide utility Dan Houston as the Eagles look toward brokering a deal with North Melbourne and the Power that would include Pick 2 and Jason Horne-Francis.

A sticking point in the discussions was seen to be the lack of value West Coast were receiving as part of the deal, despite a number of first-round selections swapping places.

It has now emerged that the Eagles could entertain the deal should the aforementioned Houston potentially be part of the trade, with the defender-midfielder hybrid landing at Lathlain Park as part of the agreement, according to AFL.com.au's Riley Beveridge.

Demon "frustrated" as club search continues

Contracted Melbourne defender Adam Tomlinson is yet to see strong enough interest emerge in his services this off-season as he continues to assess his options for 2023.

While still being signed to the Demons until the end of 2024, Tomlinson will step into the open market in hope of gaining interest and more opportunities at AFL level.

The situation has left Tomlinson to weigh up a move to a third club, having joined Melbourne from GWS at the end of the 2019 season.

Speaking on Trade Radio, Tomlinson's manager Brett Deledio revealed his client will be satisfied with remaining in red and blue, but a move away from Melbourne is desired.

"At the moment we're sort of in the hands of Timmy Lamb and the Dees, just to get something and another club to participate," Deledio said.

Three clubs reportedly interested in Crow

Adelaide midfielder Matt Crouch's future at the club remains unclear, with a trio of clubs said to be showing an interest in the contracted Crow's services.

The ball magnet is now attracting interest from other clubs for his services after Crouch fell behind the midfield chain this season under coach Matthew Nicks, in which he was omitted numerous times from the team.

According to the News Corp, the 2017 All-Australian may seek a trade in a move for more regular playing time at senior level, while three unnamed clubs circle.

Poulter waiting for call, from Pies or elsewhere

Fringe Collingwood midfielder Caleb Poulter is "hellbent on being on a list" for 2023 despite sitting under a cloud of uncertainty as he awaits a call from Collingwood and interest from rival clubs for a new contract.

Poulter is currently unsigned for next season and is no certainty to remain on Collingwood's list beyond 2022, having managed just one appearance at AFL level this year.

Poulter has been left to wait on a decision from the club but remains hopeful of continuing his AFL career, whether that be as a Magpie or not.

"It's an interesting position for Poults to be in at the moment," Poulter's manager Tim McConville revealed on Trade Radio. 

"Obviously, it's not ideal to get to this stage of the year and not have a contract.

Further reports from AFL Media claim that the South Australian could well make his way to the Suns, potentially via a trade involving Brayden Fiorini.

Lions shoot down chance of young midfielder departing

Brisbane have stated that contracted midfielder Deve Robertson is a "required player" at the Lions amid interest from West Coast.

Robertson has emerged as a target for the Eagles this year as clubs continue to circle Brisbane onballers given their own interest in Josh Dunkley and the imminent addition of Wil Ashcroft.

But despite the Eagles' advances, Brisbane list manager Dom Ambrogio has looked to end any suggestions the 21-year-old could depart for Perth.

“He's very much a required player with the Lions,” Ambrogio said of the 21-year-old.

“We only need to watch his finals series to see how valuable he is as a player to us with his defensive intent, his toughness and his two-way running.

Lions' barometer considering a trade 

Brisbane's Rhys Mathieson is reportedly "exploring a trade" this off-season as he weighs up his future in Queensland, with Brisbane confirming the midfielder could be up for grabs in 2022.

The Bell Park product is contracted for 2023, however multiple high-profile midfielders destined to join the Lions this off-season has left the 25-year-old to assess his options for next season.

The Lions are in line to land wantaway Bulldogs star Josh Dunkley in the coming days, while likely No.1 pick Will Ashcroft will join Brisbane as a father-son selection at the National Draft next month.

The situation has left Mathieson to seek a move elsewhere with a week left in the 2022 trade period, with 7 News' Mitch Cleary revealing the Victorian could join a second club after seven years in Queensland.

While Mathieson's management has "indicated" they may seek a move, an official trade request is yet to be lodged.

“His manager did indicate to us earlier this week that he may be open to one,” Lions football boss Danny Daly told Trade Radio on Thursday.
