Jarman Impey will become the seventh player to play for both Port Adelaide and Hawthorn next year.
Impey was traded to the Hawks on Thursday along with pick 67. The Power received pick 33, pick 61 and a 2018 fourth-round pick in return.
The 22-year-old played 75 games for Port Adelaide in four seasons.
In a good omen for both Impey and the Hawks, five of the other six players to represent both clubs were premiership players – Shaun Burgoyne, Stuart Dew, Brent Guerra, Stephen Gilham and Brent Renouf.
Nathan Lonie also played for both Hawthorn and Port Adelaide.
