Ryan Bird will today make his Fratton Park bow for the visit of Charlton.
The Championship side will be the first of two home friendlies for the Blues ahead of the start of the season.
Bird, who is to join Pompey on a permanent deal, has not yet returned to training following a week-long holiday in Spain.
But the striker will be on the bench today for the friendly with the Addicks (3pm).
Pompey boss Guy Whittingham is keen to get the 24-year-old integrated into the first-team as swiftly as possible after his two goals in a pre-season win at the Hawks last week.
Bird is also likely to feature in the Pompey XI fixture at Salisbury on Wednesday night as he plays catch-up.
Tom Craddock and David Connolly will lead the line against Charlton on what is also Pompey Fans’ Day.
That will leave Bird on the bench alongside fellow forwards Patrick Agyemang and Ashley Harris.
Sonny Bradley is back in contention after recovering from the hip flexor injury which kept him out against Braintree on Tuesday.
He will partner Joe Devera in the centre of Pompey’s defence – only the second time they have played together.
However, Yassin Moutaouakil sat out training yesterday as a precaution because of a tight groin.
John Sullivan will be given the full match as keeper after Phil Smith was given the nod at Braintree.
Meanwhile, Mickey Spillane’s trial at Pompey has finished.
The former Norwich midfielder had been scheduled to train with the Blues for two days – but his spell was ended after his first session.
