Pompey are weighing up their emergency loan strategy after it emerged Carl Dickinson is facing a knee operation.
The loan window opens on Monday and boss Steve Cotterill will be looking to strengthen after the Blues failed to bring in new faces on transfer deadline day.
The need to make additions has intensified with the news left-back Dickinson could have a lengthy stint out of action.
Pompey will have to juggle their loans as they already have five temporary deals in place – the maximum allowed in a matchday squad.
Cotterill said: ‘Maybe we would look to get in a loan replacement for Carl, depending on how long he’s out.
‘Would we need to bring in another left-back if Hermann performs as he did the other night? It might be another position that we need to look at.
‘We have our loans and have to bear in mind we can have only five.
‘If we take three or four we will have to leave three or four out.
‘You never know with us where we want our loans. We could do with a loan player every week.
‘We can then play them on a Saturday, send them back and then get another for the following week because that’s where we’re at.
‘It changes from day to day here. We are always desperate for one position. Whenever we put the team up, we are always desperate for one position.
‘That’s why John Utaka’s loss was such a loss. Whatever happens now, we will have a square peg in a round hole somewhere.
‘You can’t set the team up quite how you want to set the team up. It’s always been that way.’
Cotterill admits the Blues do not know the extent of Dickinson’s problem, with the loan man from Stoke expected to have an exploratory operation.
He said: ‘Carl Dickinson will be going in and having a knee operation. We know about that one.
‘It could be short-term or long-term, we don’t quite know yet.
‘He will definitely have to have something but it will just be down to the severity of what he has to have done.’
