Walsh was stretchered off in the first half of England's 1-0 win over Denmark in Sydney on Friday with what appeared to be a serious knee injury.

An England statement revealed the midfielder will not be available for the final Group D fixture against China in Adelaide on Tuesday but will continue to be assessed by the side's medical staff.

The statement read: "Following a scan late on Saturday afternoon, we can confirm Keira Walsh has not suffered an anterior cruciate ligament injury.

"Walsh has been ruled out of Tuesday's final Group D match against China in Adelaide and will remain at England's Terrigal base to continue her recovery.

"Her knee injury will continue to be assessed by England medical staff and no further update will be provided at this stage."

Walsh stretched to intercept the ball inside her own half before crumpling to the turf and immediately calling for medical attention.

She is a regular member of Sarina Wiegman's side and played a key role in England's victory at the Euros last summer.

England will be hoping the tournament is not over for Walsh, who mouthed "I've done my knee" to England's medical team as they rushed to her aid during the contest with Denmark.

There is no direct replacement for Walsh in terms of the way she dictates and controls play. She commands that role better than any other deep-lying midfielder in Europe - perhaps even the world.

So what are England's alternatives? Well, Wiegman is famed for her meticulous planning. She operates with a plan A, B and C.

During the Euros, the Lionesses sailed through the tournament with every squad member fit, which made for consistent selections. This time around they have not been so lucky.

Laura Coombs and Katie Zelem are both capable replacements - but Walsh's loss is certainly going to be felt.
