Simon Ferry is closing in on a first-team return ahead of the trip to Plymouth.
The midfielder has missed Pompey’s past two matches with the hamstring injury he picked up at York.
During his absence Thery Racon and Gavin Mahon have been signed to bolster Guy Whittingham’s midfield options.
Ferry is now nearing a training return with Pompey preparing to visit Home Park on Saturday.
Whittingham could decide the fixture has come too soon for the former Swindon playmaker.
The likelihood is Racon will return to the midfield having been rested from the Johnstone’s Paint Trophy victory at Oxford in the week.
There’s also positive news on Tom Craddock, who was another absentee from Tuesday night’s 2-1 victory.
The striker, who has suffered an injury-hit time since arriving on the south coast, has had an injection in his knee to solve a recent problem.
That should allow him to return to training ahead of Plymouth to increase Whittingham’s striking pool.
With David Connolly continuing to struggle with a calf problem, Craddock’s potential availability will be a boost to the manager’s options.
However, Patrick Agyemang and John Marquis are expected to be the striking partnership – both having netted against the U’s.
Marcos Painter remains a concern.
He hobbled out of that same match with a calf problem.
Shaun Cooper came on to replace Painter.
He could get the position again on Saturday should Painter fail to recover, although Dan Butler may also be a consideration.
Finally, Pompey’s medical team are continuing to monitor Danny East, who has been absent for the last two games.
He received a direct impact injury to his hamstring in training last week, ruling him out of a scheduled start against Rochdale.
Joe Devera and then Yassin Moutaouakil have both replaced him in subsequent matches, although Devera is likely to start against Plymouth.
