Jordon Sweet is traded from the Bulldogs to Port Adelaide in exchange for the Power's pick No.50 in this year's draft.
"Jordon has been one of, if not the premier ruckman in the VFL in 2023 and comes to our club looking for more opportunity after being stuck behind the All-Australian ruck in Tim English," Port list boss Jamie Cripps said.
"He is a mobile tall who we think will complement and develop with our young midfield, and has a mature body and enough experience to challenge to play regularly at AFL level."
