Portsmouth defender Linvoy Primus has had knee surgery in America in a bid to save his career.
Primus, 34, flew out to see renowned knee-specialist Richard Steadman in Colorado after a nightmare period on the sidelines.
The veteran remains a massive favourite with Pompey supporters despite not yet appearing in the side this season after a summer operation failed to clear up the lingering knee problem.
His agent, John Mac told the club's official website: 'I've spoken to Linvoy's wife Trish and we're awaiting updates. We don't know for sure what is going to happen until they go into his knee.
'That is the way someone like Richard Steadman works. It could be three or four different things. I guess we won't know for sure until he does it.
'It could just be a exploratory thing and he will soon be back in rehab and we are keeping our fingers crossed.'
Steadman, one of the most respected knee specialists in the world, has operated on a string of the world's top sports stars and has worked increasingly with Premier League footballers.
He has carried out surgery on the likes of Ruud van Nistelrooy, Craig Bellamy, Alan Shearer and Michael Owen, as well as former Portsmouth players Svetoslav Todorov and Patrik Berger and former Germany captain Lothar Matthaus.
Primus will spend three weeks rehabilitating at Steadman's clinic before flying back to England.
The former Pompey Player of the Year made 39 appearances last season, forming a rock-solid partnership alongside Sol Campbell. He is just three short of 200 league appearances for Portsmouth whom he joined on a free transfer from Reading seven years ago.
Primus played through the pain at the end of the season before undergoing his first operation but subsequent surgical procedures failed to put the problem right, prompting him to turn to Steadman.
Meanwhile, Pompey manager Harry Redknapp has confirmed that Premier League top scorer Benjani Mwaruwari will discuss a new contract with chief executive Peter Storrie - with 18 months still left of his current deal.
The #4.4 million signing from Auxerre is the only Zimbabwean playing in league football and has scored eight goals this season.
Meanwhile Marc Wilson, 20 year old Portsmouth midfielder, has gone on loan to League One side Luton Town after recently returning from a loan spell at Bournemouth.
