Brett Pitman is expected to return for Pompey's visit to Oldham on Saturday.
The Blues captain has missed his side's past three games, after picking up a hamstring injury in the 3-1 loss at Southend last month.
However, Kenny Jackett believes Pitman will be available for the trip to the Latics.
The Pompey boss said: 'We're hopeful for Pitman for the weekend.
'We would never take a chance with a hamstring injury, but he is due and set to do a good amount of training this week.
'I think he will be okay.'
Gareth Evans also limped off in the Roots Hall defeat with a hamstring problem and has been absent since.
The winger will again be sidelined for the clash at Oldham - but has been earmarked to return against Oxford United at Fratton Park on March 25.
Jackett added: 'Gareth Evans is probably the week after - we will see.'
