SYDNEY has announced four more list changes, with talented utility Dean Towers among the latest batch of players to be delisted by the Swans.

Jordan Foote, Angus Styles and Jake Brown have also been informed they won't have their contracts renewed by the club, adding to defender Alex Johnson's delisting last month.

Experienced forward Kurt Tippett had already announced his retirement earlier in the year.

Towers, 28, was a first-round draft pick as a mature-aged player out of the VFL back in the 2012 NAB AFL Draft and played 57 games for the club across six years.

Foote managed six matches, having been on the club's list for the last four years, while both Styles and Brown failed to make their senior debuts for the club.
