Pompey are bracing themselves for a Simon Ferry absence once more following another hamstring scare.
The Blues skipper was withdrawn on the hour mark in Thursday’s 1-0 victory over Dagenham & Redbridge.
The move was precautionary with the Scot complaining of a tight hamstring.
Ferry has suffered two previous hamstring injuries since his summer arrival and the latest incident represents a massive concern.
Marcos Painter was also substituted with the same problem, another set-back for the left-back as he attempts to establish himself with his contract soon up.
Now Richie Barker is awaiting the outcome of both ahead of tomorrow’s visit of Northampton.
He said: ‘Simon has a bit of a sore/tight hamstring, the same with Marcos.
‘We need to see where we go with that. Simon is a leader, a good captain, compliments the other people, helps them with the communication and makes decisions for people, so it will be a shame if we ended up losing him.
‘We don’t know if he will be available tomorrow, we are going to reassess both him and Painter.
‘Marcos’ contract is up soon and we will just have to see how he gets on over the next few days.
‘That is three hamstrings and a thigh in a week. Everyone else is okay, but there will be some tired legs though.
‘Although Shaun Cooper certainly won’t be fit for tomorrow – and neither will Andy Barcham.’
Cooper (hamstring) and Barcham (thigh) are not expected to play during the festive period, also ruling them out of Southend.
Now Pompey’s medical team are evaluating the potential absences of Ferry and Painter.
