The treatment room at Pompey’s training ground has been unusually busy for this stage of the season.
Tareiq Holmes-Dennis joined an ever-growing list when he limped off against Rochdale with a knee problem.
He is expected to be out for most of 2017, although fellow defenders Matt Clarke and Nathan Thompson, and winger Milan Lalkovic will be back a lot sooner.
And Kenny Jackett knows that other members of the squad have to step up to fill those places in the side.
"Injuries are part of football and you have to overcome that as a squad."
The Blues boss said: “That’s why you always talk about the whole group because you never know what’s going to happen.
“Injuries are part of football and you have to overcome that as a squad – I’ve been pleased with how the players have responded.
“We’re disappointed for Tareiq and it looks like it will be three to four months minimum, so I will be looking for another specialist left-back.
“But Brandon Haunstrup did well at Cardiff. He started off a bit shaky, but grew into the game and I was pleased with his contribution.
“We’ve been good defensively in the past two games and when we get players back we’ll be even stronger.
“Nathan has trained with the group and now it’s just about when we decide to put him in, particularly when he hasn’t played pre-season matches.”
Pompey travel to Oxford this weekend, with both sides suffering extra-time defeats in the Carabao Cup on Tuesday night.
But Jackett does not want to hear anyone talking about being tired this early in the 2017/18 campaign.
He said: “It’s poor to use fatigue as an excuse after the first week of the season.
“We battled very well for two hours at Cardiff and I certainly don’t see that being a problem. We’re here to play football.
“Oxford have a good side and can count themselves unlucky not to get into the play-offs last season.
“That’s something that they were aspiring towards as a club and I’m sure they will be again this year.
“We want to be competitive and frugal at the back, while also being more expansive on the ball with more confidence.”
