David Norris is targeting a Pompey return within the next fortnight.
The midfielder hasn’t kicked a ball since being sent off against West Ham.
He was subsequently banned for three matches for that dismissal.
It was a period the Blues used to send him to a surgeon to resolve a double hernia problem.
Norris has now missed the past six matches at a time when Pompey’s paper-thin squad is ravaged by injury,
But the summer signing believes he could be back in the next two weeks to boost Michael Appleton’s options.
He said: ‘It’s getting there, I’m looking at a couple of weeks.
‘It was a bit slow at first but is now getting a bit better day-by-day.
‘I am outside, I am running, twisting and turning a little bit with the ball.
‘I’ve got sprinting, checking and more ball work to do – then I’ll need a week’s training with the boys as well.
‘That is what will be expected of me and hopefully I’ll be okay in a couple of weeks.
‘I’m feeling stronger and my fitness will obviously need topping up but I am getting closer now.’
Norris was given a red card following a challenge on Winston Reid on January 14.
Since then Pompey have picked up four points from a possible 16.
In addition, the 10-point deduction for entering administration has plunged them into a relegation battle.
Along with Luke Varney, Norris has been a frustrated spectator during that time.
Varney, who suffered a medial knee ligament injury back in December, is also feeling his way back to fitness.
And Norris is desperate to get out playing with his team-mates again.
He added: ‘It has been so frustrating not being able to join the lads during an important time.
‘It wasn’t a straight-forward hernia operation because when I went into it I wasn’t in the best of shape.
‘Still, your body will let you know when you are ready and we will see how it goes.’
