The 32-year-old had a scan on the problem and it was discovered that his hamstring injury is more serious than first thought.
The Robins expect him to be out for up to a month but realise the former Peterborough United player will not be match fit again before the season's end, meaning he will miss the rest of the current campaign.
"The scan shows that part of the hamstring muscle has come away from the attachment and that is causing a restriction in his movement," Robins physio Ian Weston told the club's official website.
"The sciatica has cleared up but we were always dealing with two parallel injuries.
"We hoped that this soft tissue injury would clear up quickly but the scan has now shown that the problem was more serious than at first thought.
"He will make a full recovery but even if he is back in three to four weeks' time then there will not be enough time before the end of the season to get him match fit."
Defender Richard Walker, who has been out of action with a knee and thigh problem since October, will need another operation on the injury next week.
"Another scan has shown up that it is quite a serious problem and he will go in for another operation next Thursday," added Weston.
"The problem with this type of cartilage damage is that it takes a while to reveal itself.
"The operation will show whether the damage is to a relatively small area, in which case it can be repaired with something called 'microfracture surgery', or whether it affects a bigger area."
