Healy had played a leading role in putting her team on the brink of victory in the contest, hitting a brilliant 37 from just 23 balls as her excellent tournament continued.
But the Australia captain pulled up in the process of running a single off the first ball of the tenth over and was forced to retire hurt, leaving the field in clear discomfort.
The 34-year-old has endured calf injuries in the past and on first look it appeared that she had picked up a similar such injury in the incident.
And in a statement released following the game, Australia said:
“Alyssa sustained an acute right foot injury while running between wickets. Once we have more information based on her assessment and scans tomorrow, her availability for the remainder of the tournament will be clearer.”
