Matt Casey has joined Gosport Borough on loan.
The Pompey defender goes straight into Craig McAllister’s squad for Saturday’s FA Cup first-qualifying round tie at Sittingbourne.
Casey, 18, was at Weymouth on a temporary basis earlier this season but returned to Fratton Park after making just two appearances.
The Botley centre-back has now linked up with Borough on a youth loan.
It means the Blues have the option to recall Casey when he is required.
