Patrick Agyemang has returned to provide Pompey a selection boost ahead of the trip to Dagenham & Redbridge.
The powerful striker missed the weekend victory over Hartlepool having rolled his ankle in training.
It ended a run of 22 consecutive appearances for the 33-year-old, primarily as a Blues substitute.
But Agyemang was back in full training today and, along with Danny East, will be considered for selection for the trip to Victoria Road.
Definitely missing are Andy Barcham (thigh), Ryan Bird (groin) and Romain Padovani (calf).
Meanwhile, Wes Fogden and Daniel Alfei are pushing to be considered for the squad following knocks.
Andy Awford said: ‘Pat was back in training yesterday morning after rolling his ankle last week.
‘He is available for selection for Dagenham & Redbridge and Danny (East) is also with the group training again and available.
‘Wes did some light stuff yesterday morning with the physio and we are hoping if he has had no reaction he will join the group today.
‘Daniel Alfei is the same, so we will see on that one.
‘Romain is training next week with the squad.
‘I haven’t seen him since I took over as he’s been injured. He will join back in probably later next week.
‘Whether he will be ready for Bristol, I don’t know. We’ll see how that pans out.
‘Andy Barcham is still with the physio at the moment, I think he will be back this season but when it is I am not sure.
‘He has been out a little longer than a couple of the others so Bristol Rovers and Northampton will be too soon.
‘Bury is a possibility, we will see how that goes.’
Other encouraging news for Pompey is Simon Ferry has shown no reaction to his return from injury.
The midfielder played for 69 minutes against Hartlepool before being replaced by Rhys McCabe in the 1-0 victory.
It represented his comeback match after 14 games out with an on-going back problem.
Ferry has continued to train every day since and is set to keep his spot for tomorrow’s fixture against Wayne Burnett’s 10th-place side.
Awford added: ‘Simon came through the game no problem and has trained all week.
‘I was conscious we might have to give him an extra day or two, but he’s trained every single minute of every single session.’
