Oli Hawkins is not in contention for Pompey’s League One trip to Tranmere on Saturday.
The striker was substituted after suffering a blow to the head during a reserve defeat at Exeter earlier in the week.
There are no other players currently out injured, although Bryn Morris is not yet ready to make his comeback.
Blues boss Kenny Jackett said: “We’re looking good and haven’t got any new problems from last Saturday.
"We’re looking good and haven’t got any new problems from last Saturday."
“But Oli got a knock against Exeter which left him with some concussion, so he won’t be available for us.
“He’s feeling okay, although there’s a rule that means you have to rest for a few days, but he hasn’t been in the 18 recently.
“Everyone else is fit and ready to go, so we’re looking forward to making the trip to Tranmere this weekend.”
