Sydney defender Zak Jones has inked a two-year contract extension with the Swans that will see him remain at the club until at least the end of the 2019 season.

After recent speculation suggesting Jones could be heading back to Victoria at the end of the season, the 22-year-old finally put pen to paper on a new deal.

Sydney's head of football Tom Harley said the club was thrilled to keep Jones at the Swans.

โ€œZakโ€™s game has continued to develop each year heโ€™s been at the Swans,โ€ Harley said.

โ€œThis year in particular his game has added another dimension to our team.

โ€œZakโ€™s commitment is a good endorsement of the environment we try hard to foster here at the Swans and we all look forward to Zak's continued growth as a player and future leader.โ€

Jones has played 17 games for the Swans so far in 2017, and has averaged 19.8 disposals, 3.4 tackles, 4.5 marks and 3.6 inside 50s a game.
