Former number one draft pick Montana Ham has picked up another injury, suffering a foot concern that has sidelined the teenager for an extended period.

The 19-year-old managed seven games in 2022 after missing two weeks of her debut season with a knee injury. In her seven games she averaged 14 possessions a game and booted one goal for the season.

Sydney confirmed that Ham suffered a stress reaction in her left foot during a match simulation against the Gold Coast Suns.

"Montana suffered the injury in the first half of our match simulation against the Gold Coast Suns on Saturday, and scans revealed she has a stress reaction in her left foot," Swans AFLW GM Kate Mahony said.

"She has commenced her rehabilitation program and we are confident Montana will do everything possible to return to play as soon as possible."

Ham will miss the first two games of the 2023 NAB AFLW Season, after which she will be assessed to see if she can return to play.

The Swans will look towards Carlton at the SCG in a practice match on Saturday afternoon at 1:05pm AEST.

AFLW Season Eight will commence on the first week of September. The Swans will take on the GWS Giants on Sunday, September 3 in the Derby to start the year.
