Phil Brown has confirmed Rob Kiernan will miss six to eight weeks after undergoing surgery.
Kiernan has been struggling with an ongoing knee problem, but has now had an operation to rectify the issue.
In better news, Michael Turner and Michael Kightly are both in training today ahead of tomorrow’s game against Peterborough United.
Brown said: “Rob’s come back from Sweden where he’s had an operation.
“He’s had part of his tendon shaved and he’s going to be immobilised for the first two weeks, and then we will assess it after that, but he’s walking around, limping I should say.
“It’s a set back from the initial diagnosis where he went through a course of injections and that didn’t work, so it set us back for a couple of months to tell you the truth, but we went down one road of enquiry and that didn’t work, now we’ve gone down the operation line which was the last line of enquiry and it looks like the operation has been a success.
“Rob’s in a good place at the moment, but he won’t be anywhere near to us for another 6-8 weeks.
“Turner and Kightly are both training today, both training tomorrow, and then we’ll see. It’s either take a chance on an already depleted squad and then you take the chance and you make the wrong decision and someone’s out for long term and you’re back to square one.
“It’s a balancing act of whether I take a high risk or low risk and at this moment in time it’s got to be low.”
