West Ham United midfielder Katrina Gorry will miss the remainder of the Women's Super League season with an ankle injury.
Gorry sustained the injury in the 2-0 defeat by Chelsea last Sunday and left the stadium on crutches.
The 31-year-old requires surgery for the issue and her place in Australia's Olympic squad is now in doubt.
Gorry, who has 105 caps for her country, says her rehabilitation is her "next challenge".
The women's football tournament at the Paris Olympics begins on 24 August.
Australia are already likely to be without captain Sam Kerr for the tournament after the Chelsea forward ruptured her anterior cruciate ligament in January.
