Port Adelaide can turn their attention to other prospective deals, with Brisbane clearing the way on Wednesday for former skipper Tom Rockliff to join the Power as a free agent.
The Lions will receive selection 18 in next month's AFL national draft as compensation for losing the 27-year-old Rockliff, who has agreed to a lucrative four-year deal with Port.
The Lions chose not to match the offer.
"Tom had several options and we're pleased he chose us," said Port Adelaide list manager Jason Cripps.
"We're confident Tom and the club will work together and, in time, prove he made the right decision."

The Power have been linked with mercurial Geelong forward Steven Motlop and former No.1 draft pick Jack Watts, who appears to have run his race with Melbourne.
Watts had also attracted the interest of Geelong, although Cats list manager Stephen Wells said on Wednesday it was unlikely the club would be able to come up with a trade offer that would satisfy the Demons.
We've had a good conversation with Melbourne and they've made it clear what they'd be expecting from us," Wells told Trade Radio on Wednesday.
"At this stage, we don't think we'd be able to do that deal so we're not going to give Jack any false hope or waste anybody's time."
The 26-year-old Motlop has close family ties to the Power.
