Primus, who arrived at Fratton Park on a free transfer in July 2000 and is the longest-serving member of the squad, will see his duties expanded to an ambassadorial and advisory role.

The 35-year-old defender will help guide emerging talent on the south coast.

"I'm going to be working with the younger players on and off the pitch," he told the club's official website.

"I'm not going to be coaching them, I'm going to be more of an advisor, more of a mentor for them.

"I'm definitely going to finish my career here and then stay with the club when that finishes.

"In the two years that I haven't played for the first team, the club have stood by me and looked after me.

"They made sure my knee is fine and have given me an opportunity to play and also given me the chance to move into a new role."

Portsmouth have released Noe Pamarot, Lauren, Glen Little, Djimi Traore and Jerome Thomas so far this summer but aim to keep out-of-contract captain Sol Campbell.

Campbell, however, has indicated he is unlikely to stay at Fratton Park.
