Wasn't the original 1st February date for providing a funding guarantee to the EFL set (by the EFL) because that was the date the Derby administrators said they would run out of cash?
I don't see how this announcement changes much.
It probably makes it more likely than not that Derby will sell everything and everyone they can before the end of Monday (unless they can get some major loans in) to ensure they have the money to stay afloat. Hard to see any of the interested prospective buyers lending any money until or unless they get 'preferred bidder' status. Even then, a big ask as long as Pride Park is owned by Mel Morris and not the club!
