Matildas captain Steph Catley appears in doubt for Australia's Olympics opener against Germany as she battles a lower leg injury.
Catley and versatile defender Kaitlyn Torpey have both been ruled out of Sunday's friendly against Canada in Marbella, Spain with lower leg injuries.
While Torpey appears further along and likely to feature against Germany, coach Tony Gustavsson said it was 'too early to say' if Catley would be available to face Germany in Marseille on July 25 (local time).
Australia then play Zambia in Nice on July 28 then the US in Marseille on July 31.
