Cheltenham skipper John Finnigan could require an operation on his troublesome foot injury.
Finnigan has not played for almost six weeks because of the problem.
Cheltenham are unsure about the full extent of the injury and fear he may have to go under the knife, which could rule him for up to three months.
Complications"John has had some complications with his healing. Some scar tissue from the ligament tear has attached itself to the bone and is making it difficult for him to move on with the injury," Robins physio Ian Weston told the club's official website.
"There is a procedure which can deal with this but it's quite complicated so two or three specialists are going to discuss it and give us a decision next week.
"If he needs to have surgery we'd be looking at three months out because it affects a main weight bearing part of the body.
"However, there are other options and we have had some orthotics produced which will hopefully relieve some of the pressure on the foot and allow the scar tissue to heal of its own accord."
