JARED Polec announced on Wednesday that he wanted to be traded by the Brisbane Lions to Port Adelaide.

Given the glacial pace at which the 2013 Gillette AFL Trade Period had proceeded, this was seen to be big news.

Polec's announcement was greeted with excitement by the Power and widely interpreted as another sign of the shift in the balance of power in South Australian AFL football.

But before Polec thinks too much of life in the black, white and teal, there was some caution offered from the spurned Crows as well as the Lions, who hold the whip hand.

"We understand Jared has nominated a club to try to speed up the process, but the reality is no trade has been done yet," said Crows list manager David Noble.

"We'll continue to talk to Jared's management and Brisbane, and keep an eye on the situation."

His Lions counterpart Rob Kerr took a similar tack.

"Jared expressed a desire to go home, but he is not a free agent so we will continue speaking with both Port Adelaide and Adelaide," he told the club website.

Similarly, Elliot Yeo is also seeking a trade from the Lions to return to his home state and has nominated West Coast as his preferred destination.

There was no movement between the Lions and the Eagles on Wednesday despite suggestions earlier this week that the deal for Yeo was imminent.

Like his mate Polec, Yeo wouldn't want to cash all his chips with the Eagles just yet and it is understood Fremantle still remains interested in Yeo.

More certain is the destination for another disgruntled young Lion, Sam Docherty. He will be joining Carlton, with the deal not far away from completion.

Two players did move clubs on Wednesday. Hawthorn's 2008 premiership midfielder Xavier Ellis joined West Coast on a one-year contract that contains certain triggers that will extend the deal to two seasons.

But he will retire from AFL football if the injuries kick in again. "(The triggers) are achievable if the body holds up and if not, my time in the game, it's probably not for me anymore and we move on," he told Gillette AFL Trade Radio.

Melbourne picked up Fremantle midfielder Viv Michie in exchange for pick No.54 at next month's NAB AFL Draft.

The deal has been agreed to by all parties but won't be finalised until Thursday. Still, it is a good outcome for the Demons with the strong-bodied Michie, who played just one game in three years with the Dockers, likely to walk straight into Melbourne's best 22 provided he is fit and injury free.

Elsewhere, Wednesday was a day for more café lattes as the list managers continued their discussions. Greater Western Sydney's Taylor Adams inched closer to joining Collingwood, while discussions over the future of Sydney Swan Andrejs Everitt also moved along.

Paul Chapman's future was no clearer and while Essendon remains the favourite to lure the former Geelong forward, there was some love coming his way from Carlton captain Marc Murphy.

"I caught up with Mick last week and talked about a few blokes. We'd definitely be interested in having the big fella (Chapman)," Murphy said on radio station Triple M.

"Obviously, three-time premiership player and I think he kicked four goals in his last final, so still a pretty handy player."

Former Cat James Podsiadly flew into Adelaide amid great fanfare and enjoyed lunch with former Geelong colleagues Brenton Sanderson and Darren Milburn, amid talk the Crows will bring him to the club next year as the second banana to Taylor Walker.

There was no movement on the Nick Dal Santo front, but with just two days until the end of the free agency period, it is expected that discussions between St Kilda, North Melbourne and his management will heat up on Thursday.

In coaching news, after appointing Chris Fagan as general manager of football on Tuesday, Hawthorn is still deciding on how best to cover his former role as head of coaching and development.

The Hawks are weighing up whether to hire a replacement, or spread duties amongst the assistant coaching group.
