He was back on the bench at Southend on Saturday.
And now a fully-fit Brandon Haunstrup is hoping to make a return to first team action as soon as possible.
The full-back has not featured since injuring his knee in a Boxing Day victory over AFC Wimbledon at Fratton Park.
So Haunstrup knows he has to put in plenty of work at the training ground to earn his spot in the side once more.
The academy graduate said: “On a personal note, it’s good for me to be back involved with the team again.
"You can do all the running you like, but the only way you’re going to get match fit is by playing games."
“Now I need to push for a place in the side and make sure that I’m fit and ready for when I’m called upon.
“You can do all the running you like, but the only way you’re going to get match fit is by playing games.
“There’s a bit of stiffness when you first return from a mid-to-long-term injury, although I’m past that stage now.
“It’s frustrating for any player to be out on the sidelines and I was gutted when it happened to me. I’d had a run of games and was hitting some form.”
Haunstrup is hoping that Pompey can return to winning ways following a 3-1 defeat at Roots Hall at the weekend.
He said: “We started the game really well on Saturday, but then found ourselves two goals down, perhaps because of some naïve defending.
“It’s an issue we’ve got to solve and we’re working hard on the training ground to try to put that right.
“We had a good session of analysis on Sunday and it’s great that we’ve got a quick chance to redeem ourselves.
“Fleetwood have sacked their manager and that can often lead to an improvement, but we want to turn our form around.”
