The Scottish international was knocked out following a sickening mid-air collision with Rafael Da Silva but was released from hospital later on the same night after undergoing tests.
"We'll see how he is the next couple of days," said Hughton. "The good news is that he was released from hospital the same evening and travelled back to Norwich the day after. We now have to monitor how he reacts and we will make a decision on that at some point tomorrow (Friday). The X-rays came back all clear. It was always a concern when you have a clash like that. I think the ruling with concussion is a little bit different to other sports and it is really about the symptoms and whether he has any headaches or dizziness.
"We are conscious we have to make the right decision for him and his well being. He would be a doubt and so would Nathan. It's just a muscle injury around his hip, which is quite an unusual one, but you can't continue with it. He came off at the right time and it is really how quickly it settles down. He would be a doubt but as always we leave things as late as possible to give him every opportunity."
