Pompey appear set to miss out on a loan arrival before tonight’s trip to Reading.
But Stephen Henderson should be available, despite interest from up to five clubs.
Michael Appleton had been hopeful of bringing in a striker to bolster his ranks following Liam Lawrence’s departure to Cardiff.
That remains a priority area for his team, with the Blues netting just two goals in their past six matches.
However, that looks to have failed after the unnamed player’s parent club insisted he would not be available until next week.
Administrator Trevor Birch said: ‘As it stands, there will not be anyone coming in before the game.
‘We tried to get one in but he is not able to come here until next week.’
Meanwhile, Pompey’s administrator insists clubs are still coveting a number of Appleton’s players.
Henderson remains the most popular, with long-time admirers Ipswich leading the chase.
The 23-year-old reiterated to The News yesterday of his desire to remain at Fratton Park.
Yet his future is out of his hands as Pompey look to make cut backs.
Jason Pearce, Joel Ward, Luke Varney and Greg Halford are others who could also be sacrificed during tough financial times.
Birch added: ‘I am getting enquiries on a number of players. You do not need to be Einstein to work out who they may be.
‘There are four or five clubs looking at Stephen Henderson and I am not surprised because he is a great talent.
‘He has got a fantastic future ahead of him and I thought he was superb on Saturday.’
