Midfielder Gary O'Neil has become Portsmouth's latest injury victim after the 3-0 defeat at Manchester United and is a major doubt for Saturday's home clash with Fulham.
Pompey went to Old Trafford without key defenders Linvoy Primus (hamstring) and Glen Johnson (thigh), compounded when centre half Sol Campbell pulled out of the side with a stomach virus.
Now O'Neil has damaged a hamstring and admits: 'It is sore and hurting. It feels tight and I just hope it will be okay.'
O'Neil, an ever-present in the Premiership side this season, hopes he will be fit to face Fulham at Fratton Park but will need constant treatment before Pompey's medical team assess how long he can expect to be out of action.
That same team have already upgraded Johnson's previously-reported thigh strain to a torn muscle and the on-loan Chelsea right back could be out for several more games.
After Pompey's fourth defeat in six Premiership matches at Old Trafford's frustrations were compounded by his injury setback.
O'Neil admitted to the Portsmouth News: 'We had players missing on Saturday and I wanted to play if I could but the injury has probably got worse by playing.
'I was thinking if I played at United I would miss Fulham, but I will have treatment on it all week and hope to be able to play again on Saturday if I can.'
Meanwhile manager Harry Redknapp has given Bournemouth - and their boss Kevin Bond, his former number two at Fratton Park - permission to play on-loan midfielder Frank Songo'o in the first round of the FA Cup against Boston United this weekend.
