Melbourne has officially acquired off-contract Adelaide forward Shane McAdam in a trade with the Crows.

McAdam made his movement intentions clear prior to the beginning of this year's trade period; officially requesting an Adelaide departure in favour of the Demons this off-season.

On Tuesday, Melbourne put a trade offer in front of Adelaide for the wantaway Crow; one of their two future second-round draft selections.

The future second-rounder on the table will be one of two that the Demons currently possess following the club's offloading of ruckman Brodie Grundy to the Sydney Swans.

The two parties reached an agreement on Tuesday morning.

While the Dees worked to facilitate McAdam's arrival, the Crows had been intrigued by the prospect of luring South Australian Demon Harrison Petty to West Lakes this off-season, potentially as part of a deal that sent McAdam to Melbourne.

It wasn't to be, however, as the Dees remained adamant in their desire to retain Petty, particularly as he is presently under contract at Melbourne.

In other Demons player movement news, in addition to Grundy's departure, Melbourne also farewelled out-of-favour midfielder James Harmes to the Western Bulldogs in exchange for a future third-round selection last week. The club also lost James Jordon to Sydney via free agency.

Melbourne recruited Brisbane tall Tom Fullarton last Friday in exchange for Pick 47.

This year's exchange period is scheduled to conclude on Wednesday, October 18 at 7:30 PM (AEDT).
