Danny Rose has signed a one-year extension to his Pompey contract.
The new deal will keep the 30-year-old midfielder at Fratton Park until the summer of 2019.
Rose is currently recovering from a broken leg suffered in the 3-1 home victory over Northampton at the end of December.
Assistant manager Joe Gallen said: “It’s great news for us and Danny that he’s going to be here for next season.
“We’ve missed him in the team since he broke his leg and we’re pleased that he’s on the road to recovery.
"It’s great news for us and Danny that he’s going to be here for next season."
“He’s working hard in the gym and will hopefully be out running pretty soon and available for pre-season.”
Rose joined Pompey in June 2016 and played a key role as they memorably secured the League Two title last term.
The former Newport and Oxford star has scored five goals in 59 appearances during his time on the south coast.
