Ryan Taylor is eyeing a Pompey first-team return.
But the striker believes he must first come through another two training sessions to convince the management he is ready to feature.
The 26-year-old marked his return to action following a groin injury with two goals for the reserves at Cheltenham on Tuesday.
He had trained only twice before he was selected for Alan McLoughlin’s side, who ran out 3-1 winners.
But Taylor netted twice in an eye-catching 45-minute comeback display.
With Pompey struggling for goals at present, his is a timely return ahead of Saturday’s trip to York.
But he feels he must come through training today and tomorrow if he is to challenge for a squad spot.
He said: ‘It wasn’t really about scoring at Cheltenham, it was more about coming back and being injury free.
‘The groin felt fine so that is the main thing.
‘I managed to get a bit of fitness out there and hopefully am ready to train again today and see what happens from there.
‘The physios only wanted me to play 45 minutes on Tuesday so it was nice to get out there, get that in and be injury free.
‘Now I am ready to go if needed or when needed.
‘I trained for the first time on Friday last week so have only had a couple of days training and it has felt fine in those couple of days.
‘It is the same injury I’ve had a couple of times now so hopefully that is the back of it. I can put it behind me now and just stay injury free.
‘I am looking forward to getting back out there again so we will see what happens on Saturday and the next couple of weeks.
‘I don’t think Saturday is too early for me but we will see. I need another two days of training and then we will take it from there.
‘It is another long trip to York and we will be setting off early tomorrow – so hopefully I am on the bus!’
The groin problem has kept Taylor out of action for the last four matches.
During that time, Patrick Agyemang has re-established himself in the side, while Michael Drennan has returned to the club on loan.
Regardless, the lack of goals continues to be a concern for the Blues and Taylor is hopeful he is now over his injury frustrations.
He added: ‘I had more or less exactly the same thing in pre-season, only a tiny bit lower.
‘I came back from that and played quite a few games, while the manager rotated the squad pretty well.
‘He had to with the amount of games, otherwise it would have caused injuries.
‘Then I did it in training again the Thursday before the Southend game, at the end of it I just struck a ball across my body and felt my groin.
‘Hopefully that is the end of it now. I have done my rehab and it seems to have gone better.’
