David Connolly has been ruled out of Saturday’s visit of Bury as his injury problems continue.
Pompey’s joint-top scorer has now missed four matches after tearing his right calf in the 4-2 defeat at York.
The same game also saw him feel pain in his left Achilles tendon – with both issues keeping him on the sidelines since.
No date has been pencilled in for a return to Blues training and already he is out of the equation for this weekend’s Fratton Park fixture.
On a more positive note, Simon Ferry and Danny East are both expected back in training today and could be in the frame for the Shakers.
But Connolly – along with Marcos Painter and Tom Craddock – is definitely out.
Pompey physio Steve Allen said: ‘We are a little bit concerned with David.
‘He sustained a right calf tear against York and since then has also had ongoing discomfort in his left Achilles tendon.
‘We believe it has stemmed from changing from moulds into studs, with the injuries flaring up on a hard pitch at York.
‘The calf is resolving itself but the Achilles tendon is healing very slowly and there is still pain and discomfort at the moment.
‘Meanwhile, Tom has visited a knee specialist and the results have shown clinically everything is okay.
‘We have now embarked on a strengthening programme and expect him back in training next week.
‘Marcos has a calf strain and is making good progress but the timeframe is likely to be next week also.’
