Joel Amartey, Matthew Ling and Lewis Melican have all put pen to paper on new contracts with the Swans.

Melican has signed a three-year extension, keeping him in Sydney until 2023, while Amartey and Ling have signed on for a further year.

Swans Executive General Manager of Football Charlie Gardiner was thrilled with being able to secure three of the club's brightest youngsters.

“We are very excited about the young group of players we have and are committed to investing in that group to take us forward,” Gardiner told the club website.

“Lewis has overcome some injury battles in recent seasons to show us he can be a long-term key defender at AFL level.

“Matt and Joel both got a taste of senior football this season and have shown that they have exciting futures ahead of them.”

Melican was pick 52 in the 2014 draft and has played 46 games for the club since then.

Ling played his first match for Sydney in Round 8 this year against the Hawks after being drafted in 2017, whilst Amartey was a debutant in Round 20 against the Lions.
