Simon Jones' hopes of an Ashes comeback appear to have been dashed after the Worcestershire paceman was told he needs another knee operation.
The 30-year-old will undergo the procedure on Thursday and will require up to two months of rehabilitation.
Jones had been in an optimistic mood at the county's pre-season media day on Tuesday and was confident of forcing his way back into England's plans if he performed well in the early part of the county campaign.
But a visit to the surgeon on Wednesday revealed the former Glamorgan paceman has a new cartilage problem in his left knee.
Jones underwent knee surgery last September after a successful first season at New Road in which he took 42 first-class wickets in nine games.
He is unlikely to return until at least the middle of June, leaving him with little chance to stake a claim for a call-up for the start of the five-Test series against Australia the following month.
A Worcestershire spokesperson confirmed: "Simon Jones visited his surgeon today and has been informed of a new cartilage issue behind the kneecap.
"Simon will undergo surgery tomorrow and will be ruled out of playing for six to eight weeks."
Worcestershire Director of Cricket Steve Rhodes added: "It is bad news for Simon that this new problem has occurred, Simon will undergo arthroscopy on his left knee tomorrow to remove loose cartilage.
"The positive that can be taken from this is that Simon will be ready for the second part of the season."
Jones has been dogged by knee problems in recent years and has not played Test cricket since the 2005 series when he picked up 18 wickets in four matches to help England to a 2-1 success.
