Fratton Park plays host to a huge contest on Saturday, as Pompey and Charlton go in search of a crucial League One points.
Both sides are right in the hunt for the play-offs, although it is the Londoners who currently hold the upper hand.
They sit fifth following a midweek victory at Shrewsbury that saw them climb three places in the standings.
The Addicks have a couple more points than Pompey, who suffered contrasting emotions at Bradford on Tuesday evening.
Charlton’s form has improved since former England international Lee Bowyer was installed as caretaker manager – in place of Karl Robinson – last month.
It has left fans hopeful of a return to the Championship following their relegation at the end of the 2015/16 campaign.
Pompey have already beaten the Addicks twice this season, securing 1-0 wins at The Valley in the Checkatrade Trophy and league.
Curtis Main grabbed the winner in the former in November, while a Josh Magennis own-goal proved the difference the following month.
Matty Kennedy could return from a calf problem, but the Blues are still without Stephen Henderson (groin), Christian Oxlade-Chamberlain (leg), Danny Rose (leg) and Anton Walkes (hamstring).
Charlton defender Jason Pearce will make his first return to Fratton Park since leaving Pompey for Leeds in 2012.
Bowyer has stated that five of his players are struggling with hamstring injuries, but declined to reveal any names.
