Steve Cotterill has ruled out Billy Goddard winning a new Pompey deal.
The 19-year-old was a surprise face at the start of pre-season training on Monday.
He was among nine players put through their paces by Cotterill and his staff at the Wellington Sports Ground.
Goddard was one of a quartet of first-year professionals released at the end of last season.
The Basingstoke-born midfielder left along with Ellis Martin, Perry Ryan and Peter Gregory.
Despite his presence on Monday, however, it is strictly a temporary measure.
Pompey have allowed Goddard to train with them as he continues his rehabilitation from a cruciate ligament injury he picked up during a friendly at the Hawks in November.
And Cotterill has stressed there will be no deal at the end of his training stint.
He said: ‘Billy knows there is not another contract here for him but I wanted to make sure he was going to be all right before we let him go.
‘I thought that was only right and proper, really.
‘Last pre-season he got himself into a not very good physical shape, which we think perhaps contributed to his cruciate injury.
‘To be fair to him, he’s had the operation, come back and is doing really, really well. I am really pleased with him.
‘We are doing our duty of care, we are getting him up to a level of fitness where he can maybe go and get a game elsewhere.
‘He has turned his professional outlook the full circle, in my opinion.
‘He has got himself slimmed down and looks a lot better for it and stronger.
‘He will be training with the boys and doing rehab for a little while.
‘We’ll make sure he is okay and back on his feet.’
