Pompey have extended the contracts of several players to ensure they are available for the League One play-offs.
The deals of Lee Brown, Christian Burgess, Matt Casey, Oli Hawkins, Brandon Haunstrup, Adam May, Brett Pitman and Sean Raggett were due to expire at the end of the month.
However, all of those players can now feature in the games against Oxford and, should the Blues progress, the Wembley final.
The club would like to thank Norwich for allowing Raggett to complete the campaign at Fratton Park.
Luke McGee has opted not to sign an extension and will now leave the club after making 55 appearances since signing from Tottenham in the summer of 2017.
Teenage striker Bradley Lethbridge is also set to depart Fratton Park. He played three times for the first team, scoring in this season’s EFL Trophy clash with Oxford.
Portsmouth Football Club thank both Luke and Bradley for their service to the club and wish them well for the future.
