I'd be very surprised if we got a points deduction. Here's the EFL rules and regs on fixture postponement:
32 PENALTY FOR NON-FULFILMENT OF FIXTURE OBLIGATIONS
32.1 Each Club will use its best endeavours to ensure that each match under the jurisdiction of The League takes place on the date and at the time fixed for it.
32.2 Any Club failing to fulfil its fixture obligations in respect of any match under the jurisdiction of The League on the appointed date or dates or causing The League to suspend any fixture shall be deemed guilty of misconduct, unless the Club is successfully able to demonstrate that Regulation 32.2 applies . The burden of proof will rest with the Club.
32.3 The Club will not be deemed to be guilty of misconduct in accordance with Regulation 32.1 where it is able to demonstrate that:
32.3.1 the dominant and effective cause of the non-fulfilment was the occurrence of an event which was outside the control of the Club (an ‘Event’); and
32.3.2 the Club could not have been reasonably foreseen or reasonably anticipated and remediedremedy the consequences of the Event prior to the match despite using its best endeavours to do so.
32.4 The Club failing to fulfil its fixture or causing The League to suspend such fixture shall be liable to pay compensation for any expenses actually incurred by the opposing Club as a direct result of the failure or suspension. The amount of compensation will be at the discretion of the Board who will consider every such case on its merits. The Board may refer the amount of compensation to be paid to the Disciplinary Commission dealing with the misconduct by the Club failing to fulfil its fixture or causing The League to suspend the same.
Now, I'm no legal expert but I would think points 32.3.1 and 32.3.2 would cover us. If we we were given assurances about a new pitch, assurances that the pitch would be in a playable condition and that our groundstaff weren't allowed into the CBS, there's no way we can be saddled with a points deduction.
Worst case scenario, a fine and I'm sure big D will be taking that up with the 'sects.
