FRINGE Sydney duo Dan Robinson and Harry Marsh have been delisted.

Both players were former rookies at the Swans and each played 25 games for the club, including nine this season, but struggled to cement a permanent spot in the side under coach John Longmire.

Shoulder/collarbone injuries limited Robinson's chance of forcing his way into the Sydney midfield despite his prolific ball-winning at NEAFL level, and he was forced to play as a wingman or defensive half forward this year.

Marsh was a solid defender and played three finals in the club's march to the 2016 Grand Final, but he was dropped for the club's eventual loss to the Western Bulldogs when veteran Jarrad McVeigh and young star Callum Mills returned for the decider from injury.

Swans head of football Tom Harley said the pair had made valuable contributions.

"It's always a difficult time of year for a player to hear that their time at the club has come to an end," he said.

"Both Dan and Harry have been terrific members of the team and have been first-class clubmen too.

"We thank Dan and Harry for their time at Sydney and wish them all the best for the future."

The decision follows a raft of changes at the Swans, with Dan Hannebery (St Kilda), Gary Rohan (Geelong) and Nic Newman (Carlton) departing during last week's NAB AFL Trade Period.

INDICATIVE DRAFT ORDER Your club's picks

Alex Johnson, Dean Towers, Jake Brown, Jordan Foote and Angus Styles were delisted last month, while the already-retired Kurt Tippett was officially taken off the club's list.

Clubs must lodge their lists with the AFL for the first time on October 31. 

As part of the new rules ahead of the NAB AFL Draft, clubs can still trade draft picks until Friday, November 16. The draft is held over two days, beginning on Thursday, November 22.
