Pompey will continue to monitor Chris Dickson as boss Guy Whittingham explores strengthening his squad.
The striker was today expected to spend a second training session with the Blues as they run the rule over him.
He also featured for the development group in their 2-1 defeat at Leyton Orient in the week.
Dickson is hoping to tie up a move to Legia Warsaw in the next week.
But Whittingham is keeping tabs on the situation should it collapse.
The 29-year-old has the attribute of raw pace – something lacking from Pompey’s striking pool.
And with Ashley Harris out on a month’s loan at the Hawks, there is room to recruit another forward to the Blues’ ranks.
‘Chris has got pace to burn,’ said Whittingham.
‘We know that much – and he is an experienced striker, albeit abroad.
‘I think he is waiting for something abroad to happen but is training with us until that comes through.
‘It gives us a chance to have a good look at him.
‘And then if something doesn’t come up abroad then, who knows?
‘I am not saying we will do something because we have to take a lot into consideration.
‘But there is no harm in having a look at him and that is our policy.
‘If there are players out there we can look at, let’s get them in and have a look.
‘He’s done okay. He has looked a little bit rusty, I suppose because of the situation he is in (not having a club).
‘But he is a good lad, a good talker, seems a lovely character and is nice and bright.’
Dickson played for Cypriot outfit AEL Limassol in Champions League qualifiers last season.
