PORT Adelaide has parted ways with assistant coach Garry Hocking and delisted John Butcher, Kane Mitchell and Sam Colquhoun. 

Former director of coaching Shaun Hart has also been assigned to the newly formed position of director of academies, setting up and supervising Port Adelaide’s next generation academy programs.

Changes were always on the cards for the Power after they missed the finals for the second straight season.

Former Power ruckman Brendon Lade – who has been an assistant coach at Richmond - has been linked to a return to his old club.

Hocking joined the Power as a development coach in 2010 before stepping up to a role as forwards coach.

He took on the caretaker coaching role for four games in 2012 and was appointed coach of the Port Adelaide Magpies in the SANFL.

Hart had been the director of coaching with the Power since January, 2014.

The structure of the Power's football department is under review. 

"It’s a difficult time of year when the club needs to make decisions for its short and long-term future regarding our football structure," Port Adelaide’s general manager of football Chris Davies said.

"John, Kane and Sam have given great service to our club and we wish them all the best with their futures.

"Garry’s tenure at the club has been the most significant of our coaching panel. 

"We thank him for his work since 2010 as a development, line coach and Magpies coach for two seasons."

Butcher, 25, played 31 games and kicked 41 goals since debuting at the end of 2011. 

However, the key forward only played three games from rounds 18 to 20 this year. 

Mitchell, 26, was selected by the Power in the 2013 rookie draft, playing 35 games, but only four this season.

Colquhoun, 21, didn't make any appearances this season, the midfielder playing 16 games since his debut in 2013.

The Power confirmed last week that they wouldn't be offering experienced forward Jay Schulz a contract for next season.

The Power also confirmed strength and conditioning coach Mladen Jovanovic has returned to Serbia for family reasons.
