(Transfer : Accrington Stanley – Portsmouth)
Pompey have signed Callum Johnson from fellow League One side Accrington for an undisclosed fee.
The 23-year-old right-back – who has been handed the number two shirt – has penned a two-year deal, with the club holding an option for a further 12 months.
Johnson progressed through the academy at Middlesbrough and joined Accrington – initially on loan – in the summer of 2017.
The versatile defender can play anywhere across the back four and has also featured in the centre of midfield.
He made a total of 119 appearances during his time with Stanley, scoring his only goal in a 2018 victory over Forest Green.
