England's Autumn Nations Series opener with Tonga remains in a state of uncertainty with the Rugby Football Union still waiting for results from the latest round of Covid-19 testing.
Captain Owen Farrell tested positive for the virus on Friday morning and has gone into isolation.
It follows a member of the backroom team testing positive on Thursday.
The whole squad has undergone an additional round of PCR testing as a precautionary measure.
But no news is expected until Saturday morning as to who is available to face the Tongans at Twickenham.
