PORT Adelaide small forward Jake Neade has been delisted after 66 games in six seasons with the Power.

Neade was one of three Power players not offered a contract for next season on Monday, along with former Melbourne winger Dom Barry and rookie-listed midfielder Will Snelling.

Neade was linked to Collingwood during the NAB AFL Trade Period, but a deal wasn't finalised for the 24-year-old.

He played eight games for the Power this year, kicking four goals, averaging 9.9 disposals and 3.9 tackles per game.

Barry was handed an AFL lifeline by the Power when they selected him with the 61st pick in last year's NAB AFL Draft.

The 24-year-old played five games and averaged 15 disposals, but couldn't establish himself in the side.

He played five games for Melbourne between 2013-14 before taking time away from the game.

Snelling joined the Power as the 10th pick in the 2015 rookie draft.

The 21-year-old played his solitary AFL game in the Power's round 23 win against Gold Coast in 2016.

"Jake, Dom and Will have all contributed to the club in their own ways and I would like to thank them for their dedication," the Power's general manager of football Chris Davies said.

"Unfortunately, we have reached the time of the year where we have to make tough decisions regarding the future of our list.

"We wish them all the best for the future."

Meanwhile, rookie Dan Houston has been upgraded to the senior list. He played all 22 games in 2018 and won the club's best player under 21 award as well as the coaches' award as the most improved.

The Power have four players unsigned for next season – former Melbourne co-captain Jack Trengove and Trent McKenzie, and rookie-listed duo Cam Hewett and Peter Ladhams.
