Fremantle have already confirmed new jumper numbers for their trio of trade recruits ahead of the pre-season.

The Dockers managed a stellar haul through the off-season to see Luke Jackson arrive from Melbourne, Jaeger O'Meara trade Waverley for Cockburn, and Josh Corbett depart the Suns for a move west.

Their arrivals offset a quintet of departures, with Rory Lobb (Western Bulldogs), Blake Acres (Carlton), Lloyd Meek (Hawthorn), Griffin Logue and Darcy Tucker (both North Melbourne) all heading to Victoria.

With Justin Longmuir finalising his squad prior to the draft, the Dockers have begun to hand out new guernsey numbers for their three new recruits.

Jackson, who wore No.6 for the red and blue, will pull on the No.9 jumper made vacant by Acres.

O'Meara will pull on the No.2 jumper for the Dockers, a locker that was previously occupied by Logue, while Corbett has been handed the No.19 jumper, which was on offer after Connor Blakely's delisting.

Jumper numbers 12 (Mitch Crowden), 18 (Tucker) 22 (Meek), 29 (Luke Valente) and 37 (Lobb) will also be available to new Fremantle recruits.
