"He had no problems in the first half. I didn't know at the time - but he was feeling a bit sore in the second half. He didn't mention it - but then again, that's typical Martin.
"He got through the game but has felt pretty uncomfortable since.
"He went for some more scans which, at the moment, are a little bit unclear.
"He is certainly frustrated, of course, because he was doing so brilliantly.
"Considering his own injury history, he was going along nicely. Now there is a bit of frustration setting in.
"We will see - we are going to try and manage it. We are not exactly sure at this moment of what his position is. We will try and get him pain-free for the games and see if he is comfortable with that. We will take it on from there.
"Obviously we miss him because he has been such a big player for us."
