John Sheridan said "Jon is a bit sore and won't be okay,
"We are waiting for a scan and he is with the physio at the moment.
"It's unfortunate because he has a lot of bruising.
"I don't try to say how long he is going to be out or when he is going to be back – I just wait for the scan.
"He is in good hands with the physio, John (Wilson). We will wait for the scan to come back and we will have a better idea of how long he will be out for."
