Tony Gustavsson has gambled on the fitness of Caitlin Foord and Katrina Gorry, naming the injured duo in his squad for the Matildas' Olympics campaign.
Midfielder Gorry (ankle) and striker Foord (hamstring) both missed Australia's final pre-Paris hit-out against China in Sydney on Monday night.

Foord's injury is of less concern but comes with the Matildas already missing captain and chief goal-scorer Sam Kerr.
Gorry, who is arguably Australia's most influential player, hasn't played a competitive match since injuring herself playing for club side West Ham United.
"I know that this team will give everything for the coat of arms and will represent Australia to the best of their ability in the true Aussie way," Gustavsson said.
The coach named his 18-strong squad in Sydney on Tuesday, with four players selected on an "alternate" list. Courtney Nevin, retiring goalkeeper Lydia Williams, Sharn Freier and full-back Charlotte Grant are the quartet on standby.
Grant is the most unfortunate casualty having done a solid job standing in for first-choice right-back Ellie Carpenter, who missed 12 months of action in the build-up to last year's World Cup with an anterior cruciate ligament injury.
Australia kick-off their group stage fixtures against Germany in Marseille on July 25 before facing Zambia and the United States.
