Lions utility Jack Crisp completed a medical screening for the Magpies on Monday, and will become the final piece in the trade puzzle that gets Beams back to his home state.

The Jaksch trade hinged on a call from his Greater Western Sydney teammate Mark Whiley, who appeared likely to move to the Blues with him.

Carlton met Whiley's manager on Monday, having pieced together every other element of the trade. The deal would lead to the Blues gaining Jaksch, Whiley and sliding from pick seven to pick 19, with GWS taking Carlton's pick seven.

The Blues were also looking at walking Liam Jones to the pre-season draft, having failed to make much headway in talks with the Western Bulldogs regarding the uncontracted forward.

Whiley is a 190-centimetre inside midfielder, who has played 12 games in three years for the Giants since joining the club as a NSW zone selection.

The 21-year-old had attracted interest from Brisbane and Collingwood earlier in the year, but both clubs have a number of draft picks tied up in other deals and have prioritised other players.

The Lions signed Allen Christensen on Monday, sending pick 21 to Geelong, and moved closer to finalising the Beams trade with Collingwood.

The completion of that deal should see a string of connected trades start falling into place, with the Pies looking to move the Lions' pick 25 to North Melbourne for Levi Greenwood.

Collingwood would ultimately be compensated with pick five, Crisp and Greenwood for Beams, who asked the club to trade him back to Queensland at the end of the season. A later pick, in the fourth round, will probably be sent back to the Lions.

Once it completes the Beams deal, Collingwood can set about securing Travis Varcoe from Geelong, as part of a three-club trade, knowing it has the salary cap space to accomodate him.

Heritier Lumumba would move from the Magpies to Melbourne, with Varcoe joining Collingwood and Mitch Clark making his way from the Demons to Geelong.

That option would work well for the Demons, given the club is looking at using its second-round pick, 23, in a trade that would lead to Jack Trengove joining Richmond and Melbourne sliding up to take the Tigers' pick 12.

Trengove spent the weekend at home in South Australia considering his options, with the midfielder also fielding interest from Adelaide. Trengove is contracted, and could also choose to stay at Melbourne.

Port Adelaide and Essendon were no closer to reaching any deal for Paddy Ryder, after the Bombers' weekend decision not to release him as a free agent.

A number of scenarios involving other clubs, pick exchanges and Power players have been thrown up and discussed, but the Bombers have not been receptive to any of them.

Both Essendon and North Melbourne are interested in Adam Cooney, but neither club had put a satisfactory offer to the Bulldogs midfielder by Monday night and he was still considering his options.

Sam Frost is expected to make his way from GWS to Melbourne before the end of the trade period, with the Demons able to secure him in the pre-season draft is a deal cannot be reached.

A late St Kilda pick should be enough to satisfy Sydney for Tim Membrey, another pre-season draft possibility. The Swans would like a higher pick so that they could look at packaging up two selections and trading higher up the draft order.
