The 26-year old has featured five times for the Robins since arriving on loan at the end of August but has now returned to his parent club.
Speaking to the media on Thursday lunchtime, the Town boss says that the midfielder’s current ailment is a recurrence of an older injury.
“He has a problem with his foot, one which we have now discovered he has had before pre-season with Sheffield Wednesday.
“We have scanned the problem area and believe he hadn’t had a scan there before, even though he isn’t our player. He has travelled back to his parent club now and we will decide how to proceed and make the season together. They should look after him in a proper way. We did already work with him to help him - I hope they are going to do the same at Sheffield Wednesday because even if he may not be a part of their plan he is a Sheffield Wednesday player.”
When asked about Coke’s future at the club, the manager declared that he was adopting a ‘wait and see’ policy.
He continued: “We will see in the next few days. Now he go back to Sheffield Wednesday with the scan and that prove what problem he’s got because before nobody checked properly.
“I’m not accusing Sheffield Wednesday because they thought it was a simple inflammation and now they can see the real picture - thanks to us - what problem he’s got. They can see how they can proceed to help him and let him come back as soon as he can. Maybe in a few days maybe in a few weeks I don’t know.
“We will see together what we will decide over the next few days with Sheffield Wednesday and we have to decide because obviously December is far, January is far. Ok, it’s happened but we can’t leave everything like that. It’s not for me, not for us also if the club want to be sure that we got the chance to cover every position on the field.”
