West Coast has secured Port Adelaide midfielder Brendon Ah Chee from the Power.
The Eagles are expected to hand over their third round selection in next year's draft in return for the 23-year-old.
Ah Chee was searching for more opportunities after managing just five AFL games last season.
He should be able to find room in the Eagles' midfield following the retirements of Matt Priddis and Sam Mitchell.
Ah Chee played 27 games across six seasons for the Power.
