Pompey’s squad is looking in good health ahead of Saturday’s League One clash with Gillingham at Fratton Park.
Ronan Curtis, John Marquis and skipper Tom Naylor have all recovered from minor issues and are available for selection.
The former can play, despite withdrawing from Republic of Ireland international duty due to a tight hamstring.
Blues boss Kenny Jackett said: “We’re pleased that a few knocks have cleaned up and that will help us on Saturday.
“Ronan had a scan on Monday and that showed no problems after his hamstring kept him out for a few days.
"We’re pleased that a few knocks have cleaned up and that will help us on Saturday."
“The medical team’s assessment on him at the end of last week was accurate. We spoke to the Irish camp and they were happy for him to be involved for us.
“We’re obviously without Craig MacGillivray and Ross McCrorie, but are pleased with the group that’s available.
“Marquis and Naylor have both been in the treatment room, although trained on Thursday and are fine to play.
“Oli Hawkins will be the next one to come back from injury, but he is still two or three weeks away yet.”
Meanwhile, midfielder Bryn Morris is set to visit Germany next week to undergo some investigative surgery on his ongoing groin problem.
