Rob Jones will miss the rest of the season following an operation to repair his damaged neck.
Rovers staff were confident the club captain would make his comeback to the side before the end of the campaign but a flare up in the original problem on his return to training set him back.
An injection failed to remedy the problem and he will now require surgery, the recovery time for which involves three months rest, ruling him out for the rest of the campaign.
Rovers physio Alex Dalton said: “Rob had a cervical nerve route block injection but unfortunately it has not had the desired effect, which means that he will more than likely have to have a neck operation.
“This is a cervical fusion to rectify the problem.
“He goes down this week but it will probably be early next week when he has the operation.
“After this it‘s three months complete rest, so we then look to next season for him.”
Fellow long-term injury victim Jamie McCombe has been cleared to return to light training following a set-back in his recovery from a spinalb issue.
Dalton said: “Jamie has been to London to see a sports medicine doctor and is pain free, so is doing well at the moment.”
