Richie Barker will give Ryan Taylor the opportunity to prove his fitness for the weekend trip to Scunthorpe.
The Blues striker was substituted on Saturday with a groin problem, having scored the only goal of the game in the 1-0 win over AFC Wimbledon.
While the 25-year-old has not trained since, he does not require a scan, though.
And the Pompey boss is hopeful his striker will be fit for the weekend trip to Scunthorpe.
Barker also hinted that he expects the former Bristol City man to declare himself fit.
‘Ryan hasn’t trained just yet but we will be having a look at him tomorrow morning,’ said Barker.
‘We didn’t expect him to be training in the first part of the week, to be fair.
‘We wanted to give him a chance to rest it and we didn’t need to rush him.
‘He hasn’t needed a scan. It’s just a small issue.
‘At the moment, we’re hoping it’s not as serious as we thought it might be. We’re hoping it was caught early enough. But strikers tend to want to keep playing when they are scoring goals.’
In further good news for Barker, three more of his players are closing in on a return after injury lay-offs.
Simon Ferry (back) is expected to be in contention this weekend, while Joe Devera and Danny East (both ankle) are set to step up their recoveries.
Barker added: ‘Joe hasn’t trained since he was injured at Exeter, but he will be doing some running this week and we will see how he is.
‘At the time, we thought he’d done something to his knee but he actually hurt his ankle in the same incident.
‘But Danny East has started running again and Simon Ferry is back in training.
‘We’re getting there.’
