There was growing concern that Oli Hawkins had become the latest player to join the packed Pompey treatment room.
The towering striker limped off after an hour of Saturday’s disappointing home defeat to Blackpool.
He injured his knee during the first half of the Fratton contest, battling on before ultimately having to be withdrawn.
But Kenny Jackett does not believe it will keep him sidelined for long and hopes Hawkins will be able to feature at Bradford on Saturday.
The Blues boss said: “He was treated twice in the first half for a knee injury and again at the break.
“It was just too painful for him in the end. It was deteriorating and he’s a big lad, so there’s a lot of weight on his knees and ankles.
"We’re certainly not diagnosing any long-term problems and we are confident it will clear up pretty quickly."
“Unfortunately he eventually had to come off, but we’re hopeful that he’ll be okay for this weekend.
“We’re certainly not diagnosing any long-term problems and we are confident it will clear up pretty quickly.”
Kal Naismith recovered from a groin problem to make an appearance from the bench against the Seasiders.
Jackett said: “We haven’t got many senior players in the forward department and so we’ll definitely be looking for him now to make an impression.”
