Port Adelaide has delisted Joe Atley, Riley Grundy, Tobin Cox and Wylie Buzza.
Atley, the brother of North Melbourne defender Shaun, played four games since debuting in 2017.
Grundy, the brother of Collingwood ruckman Brodie, and Cox didn’t manage a senior appearance for the club.
Buzza joined the Power from Geelong as a delisted free agent at the end of 2019.
The 24-year-old ruck/forward didn’t appear for Port in his one and only season at Alberton.
Power GM of Football Chris Davies said: “We’ve reached the time of the year where we have to make difficult decisions about the direction we take with our playing list.
“I would like to thank Joe, Riley, Tobin and Wylie for their efforts and professionalism during their time at the club, and the contribution they have made to our group.
“They will always be part of the Port Adelaide family, and we wish them well for the future on and off the field.”
