Port Adelaide has reached an agreement with Richmond to acquire ruckman Ivan Soldo, officially lodging a deal at AFL House on Wednesday afternoon.

The Tigers, who were thought to not be interested in offloading the contracted 27-year-old, backflipped and agreed to send the mulleted tall to Alberton.

Port Adelaide has attained Soldo and this year's No. 50 draft selection. In exchange, it will send this year's No. 41 and 49 selections, Fremantle's future second-rounder, as well as its future fourth-round pick back to Punt Road.

The Power, whose higher-ups have a host of business to sort through, will also be looking to nab wantaway Western Bulldogs ruckman Jordon Sweet on deadline day.

Sweet, though, is not contracted, which should make negotiations slightly more straightforward than the Power's Soldo acquisition.

The early morning agreement with Richmond also provides Port Adelaide plenty of time to negotiate with the Western Bulldogs, Geelong, and Essendon for Sweet, Esava Ratugolea, and Brandon Zerk-Thatcher, respectively.

The trade period concludes Wednesday at 7:30 PM (AEDT).
