The City forward, who is also her nation’s leading scorer, withdrew from the Lionesses’ squad last week after testing positive for COVID-19.
It meant that she missed England’s 5-1 win over the Netherlands at Leeds’ Elland Road in which Lauren Hemp grabbed one goal and one assist.
And while Wiegman confirmed that White had been able to maintain her fitness during her time away from the squad, she tempered expectations on whether the striker would feature in Zurich.
She said: “(Ellen’s) good. It took a while, but we’re glad she’s back and she’s very happy too. Hopefully we can build her up again and get her ready for the Euros.
“Yes, she did (train at home), maybe one or two days she took it easy and then she trained by herself.
“She’s in shape but I don’t know yet, let’s first start and see how she is on the training pitch and start up.
“She hasn’t been in training for a week now, so we don’t take any risks.”
The England boss also revealed that former City defender Lucy Bronze was set to miss tomorrow’s friendly due to illness, but that it was not COVID-19 related.
