NEW DELHI: Australia will be without captain Alyssa Healy for Wednesday's ICC Women's World Cup match against England in Indore, as she is sidelined with a calf injury. Tahlia McGrath has been named to lead the seven-time champions in her absence.

Healy, who had delivered back-to-back centuries in Australia's previous two matches, sustained the injury during a training session on Saturday, forcing her out of the high-profile encounter.

"Yeah, obviously really unfortunate there for her with just a slight calf strain," Australia head coach Shelley Nitschke said at the pre-match press conference on Tuesday.

The 35-year-old, who has battled injury in recent times, will continue to be monitored, but she could be in a race against time to be fit for the semifinals scheduled for next week. Before that, table toppers Australia face South Africa in their final league match on Saturday.

"We're just going to keep assessing her day by day and give her every opportunity to play the next game against South Africa and just see how that plays out over the rehab, but just keep assessing and hopefully she gets up," Nitschke said.

With 294 runs from four innings, Healy is currently the leading run-scorer in the tournament. In her absence, Georgia Voll is expected to open alongside Phoebe Litchfield against England.

"We've got some options. Obviously, the one is Georgia Voll that's here and has filled that role before, but we'll sit down today and probably just make sure we're getting our matchups right and come to a final decision.

"But we've certainly got some depth there in our batting, so there is some opportunities outside of that move as well," Nitschke said.
