Pompey are still not sure how long they will be without skipper Clark Robertson.
The defender is waiting to hear from a specialist after missing Saturday’s defeat to Cambridge at Fratton Park with a hip problem.
Connor Ogilvie – the only other naturally left-sided centre-back option – was also absent with a quad injury.
And Danny Cowley will once again be without the duo when Plymouth travel along the south coast on Tuesday night.
The Blues boss said: “Clark has a tendon issue in his hip and is a real loss for us. We still don’t know how long he’s likely to be out for and are getting a specialist opinion.
"Injuries are a part of football, so you can’t moan about them. The important thing is to find a solution."
“He’s our captain and has had an outstanding start to the season – you never want to lose a key player.
“Connor is also a big loss for us, although hopefully he won’t be missing for too long and is doing some gym work.
“Injuries are a part of football, so you can’t moan about them. The important thing is to find a solution.
“Everyone else trained on Monday and I saw a real desire from the boys to put right the wrongs of Monday.
"Joe Morrell also didn't start the Cambridge game because of a bereavement in the family and we send our love to them."
