Pompey's future remains uncertain after former owner Balram Chainrai withdrew his offer to buy the club, but the Pompey Supporters' Trust remain hopeful of completing a takeover.
The south coast outfit face another 10-point deduction but the Football League say that will not come into effect until the club exits administration, meaning they will begin the League One season on zero.
Meanwhile, administrator Trevor Birch has told first team boss Appleton he can begin signing players on one-month deals ahead of Saturday's League One opener against Bournemouth at Fratton Park.
Appleton has a host of experienced free agents currently training with the club, including Jon Harley, Brian Howard and Izale McLeod, but having been unable to offer them contracts he was forced to field a virtual youth side in the 3-0 Capital One Cup defeat at Plymouth on Tuesday night.
But Birch told The News: "We can sign players and are attempting to sign them between now and Saturday - but only on a monthly contract."
