The Blues sealed the last trade of the day when it received Warnock and a fifth-round selection (No.69). In return, Carlton gave Fremantle three draft selections – No.24 (round two), No.56 (round four) and No.72 (round five).
As for Sydney Swans 2005 premiership player Ryan O'Keefe, he didn't find a new home. A deal between Hawthorn or Carlton did not eventuate and it remains to be seen what happens to the classy forward.
He is out of contract and could try his luck via the draft system or remain in the harbour city.
Melbourne leader Brad Green is likely to remain a Demon for life after he signed a new three-year deal just before the trade window closed. It was a fine result for Melbourne considering Collingwood, the Sydney Swans and Hawthorn were all hovering during the week.
North Melbourne's Daniel Harris, Essendon's Andrew Lovett and West Coast's Mark Seaby all remain with their respective clubs.
The Warnock deal was one of six trades to occur throughout the exchange period, capping off a quiet week. The predominant reason for little action is due to clubs wanting to hold onto their picks, with the upcoming NAB AFL Draft being the last of the uncompromised meetings. The introduction of the Gold Coast into next year's draft meant clubs were eager to hold onto their picks.
Still, there was a flurry of action between 11.45am and 12pm on Friday, when three deals were sealed.
The first happened when Collingwood traded Rhyce Shaw and round four (No.61) to the Swans.
At 11.55am, Collingwood gained Brisbane Lions utility Anthony Corrie for pick No.93, a round-six selection. Collingwood views Corrie as a bargain basement selection, and it is considering the Lions are highly unlikely to utilise No.93.
This transaction was a win for the 'goodwill' rule introduced last year, when clubs were allowed to trade a player for a pick, yet it does not have to use that selection at the draft.
Just before midday, Western Bulldogs midfielder Farren Ray became a Saint. The Dogs also gave St Kilda pick No.48. In return, the Bullies gained selection (No.31).
Although the Dogs initially wanted to retain Ray, they agreed to move on the Western Australian, who wanted to purse opportunities elsewhere, when the Dogs got the second-round choice it was after.
In the last 10 minutes of the trade period, Brent Prismall became a Bomber when Geelong gave him up for a third-round selection (No.35).
The midfielder was strongly pursued by Melbourne, but in the end the Dons got their man. Luck wasn't on Prismall's side when he injured his knee in Geelong's qualifying final after just breaking into the strong Cats' line-up. It is unknown how much time Prismall will miss in 2009.
The only trade to happen before the final day was on Thursday, when Richmond claimed Port Adelaide midfielder Adam Thomson. The Power received a round-three selection (No.42).
