Goalkeeper Hannah Hampton is undergoing treatment for an ankle injury.
Hampton suffered the damage when away with England during the SheBelievesCup tournament in America.
Due to the restrictions caused by COVID-19 virus, her rehabilitation won't be as straight forward as normal.
"Hannah injured her ankle ligaments when away with England," confirmed Interim Head Coach Charlie Baxter.
"We aren't able to speculate on the timescale.
"It's an unusual situation in that we have to ensure there are no health and safety concerns around her rehabilitation programme for herself and the medical staff.
"So we are handling that carefully and the main thing is that we do everything correctly."
The break in the Barclays FA WSL and FA Cup programme means that Chloe Arthur will be fully recovered when normal activities due resume again.
Arthur suffered a head injury at Chelsea and concussion protocols meant she missed the next two Blues games.
She had to pull out of the Scotland squad for their successful Pinatar Cup tournament in Spain and the midfielder would not have featured in the FA Cup Quarter-Final at Brighton & Hove Albion.
"Chloe was on a 'return to play' training plan before our last game was postponed," said Baxter.
"We were getting her back on the pitch with a view to recovering her sharpness.
"Physically she will be fine and it's just a case of her continuing with the training and strength and conditioning programme she's on at the moment."
"Injuries are part and parcel of the game. It is what it is - you just have to deal with them.
"Obviously we don't know yet when we can return to full training. But I'd like to think that we will be in pretty good shape injury wise when we are back in."
